Question

1. The base area of a cone is 38.5 cm.
Its volume is 77 cm. Find its height.​

Answer 1

Answer:

h=6

Step-by-step explanation:

Base area = πr² = 38.5 cm²

volume = (1/3)πr² ×h = 77 cm³

so, A/q

77 = (1/3) ×38.5×h

⇒h = (77×3)/38.5

    h= 6 cm.

Answer 2

Answer:

Base area πr^ =38.5cm^ and volume 1/3πr^h= 77

Step-by-step explanation:

Then 77 = 1/3πr^h =h=77×3/38.5 =6cm
