Question

A cylinder has a radius of 8 cm and a height of 14 cm.

What is the volume of the cylinder?
A. 112pi cm^3
b. 224pi cm^3
c. 896pi cm^3
d. 3584pi cm^3

Answer 1

here the volume V of a cylinder is giben by the subsequent formula:
\[V = \pi \times {R^2} \times H\]

Answer 2

ok - you don't need to work out the answer using pi - you can see that all the answers have pi left in

so volume of a cylinder is th earea of the circular end times the height

so area of circle = pi * r^2

so volume = pi * r^2 * h

in your case
r=8
h= 14

so put those number s into pi *r^2*h to get the right answer...

Answer 3

wher R is the radius, namely R= 8 cm, and H is the height of our cylinder, namely H=14 cm

Answer 4

so, substituting, we get:
\[V = \pi \times {R^2} \times H = \pi \times {8^2} \times 14 = 896\pi \;{\text{c}}{{\text{m}}^{\text{3}}}\]

Answer 5

@Michele_Laino ya this is the last question in the chapter practice, also did anyone else got booted off the site temp?

Answer 6

volume of cylinder is v=pi*r*r*h
where r is radius and is height
