Question

Find the volume. Help asap. Please.

Answer 1

Use the Pythagorean theorem to find the diameter:

Diameter = √(19.3^2 - 9.5^2)

Diameter = √(372.49 - 90.25)

Diameter = √282.24

Diameter = 16.8 m

Volume of a cylinder = PI x r^2 x h

r = 1/2 diameter = 16.8 /2 = 8.4

h = 9.5 m

Volume = PI x 8.4^2 x 9.5

= PI x 70.56 x 9.5

= PI x 670.32

In terms of PI volume = 670.32PI

As a decimal:

670.32 x 3.14 = 2104.8048 = 2100m^3 ( rounded to the nearest hundred)

Answer 2

Hey!

------------------------------------------------

First, we need to find the diameter.

d = √a² - b²

d = √19.3² - 9.5²

d = √372.49 - 90.25

d = √282.24

d = 16.8

Second, find the the radius.

radius = 16.8 / 2

radius = 8.4m.

Third, find the volume.

v = πr²h

v = (3.14)(8.4)²(9.5)

v = (3.14)(70.56)(9.5)

v = 670.32π

v = 2,104.8048...

2,104.8048... ≈ 2,100m.

Answer:

2,100m.
