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

In ABC, b = 68 inches, B=65° and C=93º. Find the length of a, to the nearest
inches

Answers

Answer:

28inches

Step-by-step explanation:

∠A + ∠B + ∠C = 180°

∠A + 65° +93° = 180°

∠A + 158° = 180°

∠A= 180°-158° = 22°

Using Law of Sines

a/sinA= b/sinB

a/sin22= 68 inches/sin65

a/sin22 = 68/0.9063 = 75.03

a = 75.03 x sin 22

a = 75.03 x 0.3746 = 28.106238≈28 inches

Answers

Answer: 25 sixth graders

Step-by-step explanation:

Sixth-graders are in a ratio with fifth graders in the band at 5:4 and there are 20 fifth-grade students in the band.

To find the number of 6th graders, use direct proportion and assume the sixth grader number is x:

5                   :            4

x                    :            20

4x = 100

x = 100 / 4

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]

width = 126 ft

Step-by-step explanation:

I'm going to assume that I am solving for width.

Area = width x length

84 = 2/3 x width

Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)

84 x 3/2 = width

width = 126 feet

Three adjacent lots had road frontage measured to be 200.1 ​ft, 135.45 ​ft, and 55.133 ft. What is the total length of the frontages of these three​ lots? Round off your results to the proper degree of precision.

Answers

Answer:

470 feet

Step-by-step explanation:

Given that,

Three adjacent lots had road frontage measured to be 200.1 ​ft, 135.45 ​ft, and 55.133 ft.

We need to find the total length of the frontages of these three​ lots. It can be simply calculated by adding these three lengths ie.

Total length = 200.1 ​ft + 135.45 ​ft + 55.133 ft

= 471 feet

or

= 470 feet

So, the total length of these three lots is equal to 470 feet.

The length of a rectangle 5 cm more than its width. If the area of the rectangle is 50 cm2
,
find the dimensions of the rectangle.

Answers

Answer:

the length is 10

the width is 5

Step-by-step explanation:

Hey there!

To solve this equation we use the formula

50=5/x

step 1 divide each side by 5

50/5=10

so we can conclude that x (or the width) = 5

then we add 5 (because the length is 5 more then the width)

5+5=10

so length =10 and width = 5
