Question

1 . if the volume of the cylinder 385cm^2 and its height is 10 cm find its base area and base redius
2.if the volume of the cylinder 1078cm^2 and it's height is 7 cm find it's base area and base redius
​

Answer 1

Answer:

Base radius is 3.5 cm

Step-by-step explanation:

part 1

volume of cylinder = π r ² h

here r = radius , h = height, value of π = 22/7 (known constant)

385 square cm = volume given

h = 10 cm given

r = to find

385 = 22/7 x r ² x 10

385 = 220/7 x r ²

r ² = 385 x 7/220 = 2695/ 220= 12.25

r = $\sqrt{12.25}$

r = 3.5 cm answer

now following the same approach you can find solution to part 2 . all the best you can do it.
