The height of a cone is equal to the diameter of the base.
(2x height, x radius)
what expression represents the volume of the cone, in cubic units?
a. 2/3 πx^3
b. 4/3 πx^2
c. 2πx^3
d. 4πx^3

we know that

the volume of a cone is equal to

where

r is the radius of the base of the cone

h is the height of the cone

in this problem we have

substitute in the formula

therefore

the answer is the option A

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
