Question

What is the volume of a cone with a radius of 2 and a height of 19?
A. 79.59 units3
B. 238.76 units3
C. 39.79 units3
D. 722 units3

Answer 1

Answer 2

volume of the cone is= (pi x r^2)H/3
therefore if r=2 H=19 pi=3.14
so the answer is A=79.59 units3

Answer 3

The formula for volume of cone is

V = ( h x A)/3 , where h is the height of the cone
A is the area of the base , which is equal to
A = pi x r^2 , where r is the radius

V = (h x pi x r^2) / 3

Assume pi = 3.1416

V = (19 x 3.1416 x (2)^2 )/3
V = (19 x 3.1416 x 4) /3
V = 238.762/3
V = 79.59 units 3

Answer 4

\[v=1/3 \pi r^3h\]
\[1/3 \times \pi \times 2^3 \times 19\]
can u solve it further
