Question

Which expression can be used to find the height of the cone below?

V = 30ft³ B = 80ft²
A.30 = 1/3(8h)
B.8 = 30h
C.30 = 8h
D.8= 1/3(30h)​

Answer 1

A. 30 = ⅓(8h)

Explanation:

Volume of cone (V) = 30 ft³ (given)

Base area (BA) = 8 ft² (given)

height = ?

Formula for volume of a cone = ⅓*B.A*h

Plug in the values into the equation

30 = ⅓*8*h

30 = ⅓(8h)

Expression to find the height will be 30 = ⅓(8h)
