A. Directions: Find the surface of the following. Round your answer to nearest
hundredths. (Use n = 3.14) Write your answer in your notebook.
1) cone with radius of 15 cm and slant height of 12 cm
2) cone with radius of 8 cm and slant height of 11 cm
3) sphere with radius of 3.2 cm
4) sphere with diameter of 6 cm
Answer:
1. S.A of a cone = 565.56 cm².
2. S.A of a cone = 276.496 cm².
3. S.A of a sphere = 128.696 cm².
4. S.A of a sphere = 113.112 cm².
Step-by-step explanation:
Given the following data;
1. Radius, r = 15cm
Slant height, l = 12cm
Mathematically, the surface area of a cone is given by the formula;
Surface area of a cone = πrl
Substituting into the formula, we have;
S.A of a cone = 3.142 * 15 * 12
S.A of a cone = 3.142 * 180
S.A of a cone = 565.56 cm²
2. Radius, r = 8cm
Slant height, l = 11cm
Surface area of a cone = πrl
S.A of a cone = 3.142 * 8 * 11
S.A of a cone = 3.142 * 88
S.A of a cone = 276.496 cm²
3. Radius, r = 3.2 cm
Mathematically, the surface area of a sphere is given by the formula;
Surface area of a sphere = 4πr²
Substituting into the formula, we have;
S.A of a sphere = 4 * 3.142 * 3.2²
S.A of a sphere = 4 * 3.142 * 10.24
S.A of a sphere = 40.96 * 3.142
S.A of a sphere = 128.696 cm²
4. Diameter, d = 6cm
Radius, r = diameter/2 = 6/2 = 3 cm
Surface area of a sphere = 4πr²
S.A of a sphere = 4 * 3.142 * 3²
S.A of a sphere = 4 * 3.142 * 9
S.A of a sphere = 36 * 3.142
S.A of a sphere = 113.112 cm²

D
Answer:
C
Step-by-step explanation:
1. The domain is the x-value of a function.
2. In that image, the x-values are the numbers on the left of each parenthesis.
3. You should put the domains in increasing order, so the final answer is -2, 0, 2, 4.
The function p(h)=0.375h+3 represents the supply model to determine the millions of
available workers with the minimum hourly wage,h. Find the number of workers when the
minimum wage is $5.15 per hour. Round to the nearest hundredth place.
Answer:
4.93 million workers
Step-by-step explanation:
0.375*5.15+3 = 4.93125
The number of available workers is 4.93
The given expression:
[tex]p(h) = 0.375h + 3[/tex]
where;
h is the minimum hourly wage = $5.15
To find:
the number of workersThe number of available workers is calculated as follows:
[tex]p(5.15) = 0.375(5.15) + 3\\\\p(5.15) = 4.931\\\\p(5.15) \approx 4.93[/tex]
Thus, the number of available workers is 4.93

Write the equation of the circle containing the point (8, 1) and a center at (4, –9).
9514 1404 393
Answer:
(x -4)² +(y +9)² = 116
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)² +(y -k)² = r² . . . . . . center at (h, k), radius r
The value of the r² term can be found by using the point in the circle expression.
(x -4)² +(y +9)² = (8 -4)² +(1 +9)² = 16 +100
(x -4)² +(y +9)² = 116 . . . . . equation of the circle

Recall that Rn denotes the right-endpoint approximation using n rectangles, Ln denotes the left-endpoint approximation using n rectangles. Calculate the approximation for each of the given function and interval below. (You may use calculator and keep the final numerical answer in decimals for this question) (a) (3 pts) R5, f(x) = x 2 + x on the interval [−1, 1]
Answer:
[tex]R_5=1.12[/tex]
Step-by-step explanation:
We want to calculate the right-endpoint approximation (the right Riemann sum) for the function:
[tex]f(x)=x^2+x[/tex]
On the interval [-1, 1] using five equal rectangles.
Find the width of each rectangle:
[tex]\displaystyle \Delta x=\frac{1-(-1)}{5}=\frac{2}{5}[/tex]
List the x-coordinates starting with -1 and ending with 1 with increments of 2/5:
-1, -3/5, -1/5, 1/5, 3/5, 1.
Since we are find the right-hand approximation, we use the five coordinates on the right.
Evaluate the function for each value. This is shown in the table below.
Each area of each rectangle is its area (the y-value) times its width, which is a constant 2/5. Hence, the approximation for the area under the curve of the function f(x) over the interval [-1, 1] using five equal rectangles is:
[tex]\displaystyle R_5=\frac{2}{5}\left(-0.24+-0.16+0.24+0.96+2)= 1.12[/tex]

C
Answer:
A = 154°
B = 26°
C = 154°
Step-by-step explanation:
✔️A = 180° - 26° (angels on a straight line)
A = 154°
✔️<B and 26° are vertical angles. Therefore,
B = 26° (based in the vertical angles theorem, vertical angles are congruent to each other)
✔️C = A (based in the vertical angles theorem, vertical angles are congruent to each other)
Substitute
C = 154°
Ashleigh wants to find the volume of her green house. The green house is the shape of a rectangular prism. It has a length of 18 feet and a width of 12 feet, but she cannot measure the height. She can tell that it is about half measurement of the length. Describe the steps Ashleigh should take to get an estimate of the volume.
9514 1404 393
Answer:
1944 ft³ using the estimated height
Step-by-step explanation:
Ashleigh can use her estimate of the height, along with the other dimensions, in the volume formula to get an estimate of the volume.
V = LWH
V = (18 ft)(12 ft)(9 ft) = 1944 ft³

Answer:
6 × 5
Step-by-step explanation:
If you want to reduce the fraction 12/30, you want to find the greatest common factor of 12 and 30. We can find that by looking at the prime factorization of each number.
12 = 2·2·3
30 = 2·3·5
The greatest common factor is 2·3 = 6. This means ...
[tex]\dfrac{12}{30}=\dfrac{12}{6\times5}[/tex]
The product of interest is 6 × 5.
_____
Additional comment
Any of the factor pairs of 30 could be used. Only the one shown is useful for reducing the fraction to lowest terms.
30 = 1×30 = 2×15 = 3×10 = 5×6
Scientists are studying a bacteria sample. The
function f(x) = 245(1.12) gives the number of
bacteria in the sample at the end of x days.
Which statement is the best interpretation of one of
the values in this function?
The initial number of bacteria is 12.
The initial number of bacteria decreases at a rate of 88% each
day.
The number of bacteria increases at a rate of 12% each day.
The number of bacteria at the end of one day is 245.
The best interpretation of one of the values of the function is that the rate increases by 12% each day.
