Isabella uses the equation V = one-third (12) squared (9) pi to find the volume of the cone below.

A cone has a height of 9 centimeters and base of 12 pi centimeters squared.

What is Isabella’s error?

A. Isabella should have divided 12 by 2 before squaring to get V = one-third (6) squared (9) pi.

B. Isabella should have squared 9 instead of 12 to get V = one-third (9) squared (12) pi.

C. Isabella should have divided the product of 12 and 9 by 3 to get V = StartFraction 12 (9) Over 3 EndFraction.

D. Isabella should have divided the product of 12 pi and 9 by 3 to get V = StartFraction 12 pi (9) Over 3 EndFraction

(D)Isabella should have divided the product of , and 9 by 3 to get .

Step-by-step explanation:

Isabella uses the expression: to find the volume of a cone with the following dimensions:

Height=9cm

Base Area =

Volume of a Cone ,

Since the base area of the cone =, Isabella should have divided the product of , and 9 by 3 to get .

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
