Question

A cylinder with a height of 9cm. And a width of 10cm. Find the exact volume.

A. 90pi cm^3
B. 45pi cm^3
C. 900pi cm^3
D. 225pi cm^3

Answer 1

Answer: D) 225pi cm^3.

Explanation:

Answer 2

The correct answer is D. 225pi cm^3.

To find the volume of a cylinder, you use the formula:

V = πr^2h

Where V is the volume, π is pi, r is the radius of the base, and h is the height of the cylinder.

In this case, the height is 9cm, and the width is 10cm. To find the radius, we divide the width by 2:

r = 10cm / 2 = 5cm

Now we can plug in the values into the formula:

V = πr^2h

V = π(5cm)^2(9cm)

V = π(25cm^2)(9cm)

V = 225π cm^3

So the volume of the cylinder is 225π cm^3
