Explanation:
The area of a circle is pi times the radius squared (A = π r²).
Our radius is 7.1 so we square it which is basically the equivalent of doing 7.1 x 7.1 which equals 50.41 then we multiply this by pi which is 3.14 so it 50.41 x 3.14 = 158.2874
Area:
= 3.14 x (7.1)²
= 3.14 x 50.41
= 158.2874
= 158.29 (nearest hundredth)

Kim is creating a mosaic in her garden. She finds the tile below and wants to know the missing side length ‘x’. Calculate the missing side length to a reasonable level of accuracy, explain your decision.
Answers
Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm

Find the volume of a cylinder having a height of 105 millimeters and a base with a diameter of 40 millimeters. Use the volume formula and 22/7 for π.
Choose the values for r and h. (1 H and 1 R)
h = 22/7
h = 105
r = 20
r = 40
Answers
Answer:
132,000 millimeters squared, H= 105, R= 20
Step-by-step explanation:
Volume equation (r= radius, h = height)
v= (pie)x r^2 x h
Pie = 22/7
r = 1/2 the diameter, so 40/2= 20. r = 20
h = 105
Substitute
(22/7) x 20^2 x 105
20^2 = 400
(22/7) x 400 x 105 = 132,000

Answer:
Heyya little student!
Sin means [tex]\frac{opposite }{hypotenuse}[/tex]
5 is the hypotenuse (its opposite to 90 degrees )
So, sin β would be:-
the side opposite to the angle β divided by the hypotenuse of the triangle.
The side opposite to β is 4
and as I said earlier, the hypotenuse is 5
So, sin β would be:-[tex]\frac{4}{5}[/tex]I hope it helped you!

A cookie jar contains 6 sugar cookies, 4 lemon cookies, and 2 chocolate cookies. Anne randomly chooses 1 sugar cookie from the jar, replaces it, then chooses a chocolate cookie.
1/11
1/12
8/23
1/3
Answers
Answer: 1/12
Step-by-step explanation:
Number of sugar cookies = 6
Number of lemon cookies = 4
Number of chocolate cookies = 2
Total number of cookies = 6+4+2 = 12
The probability of firs choosing a sugar cookie will be: = 6/12 = 1/2
The probability of then choosing a chocolate cookie will be: = 2/12 = 1/6
Then we multiply both probabilities together and this will be:
= 1/2 × 1/6
= 1/12
