Question

If the volume of an cylinder is 700 cubic cm and the area of the base is 100 square cm what is the length of the cylinder?

Answer 1

Step-by-step explanation:

volume of cylinder=700cm³

base of cylinder =100cm²

we know that base of cylinder is circle.

so,

area of circle= πr²

100=22/7 r²

r²= 700/22

Then,

volume of cylinder= πr²h

700 = 22/7×700/22×700/22×h

calculate we get

h= 22/100

so,

length= 0.22cm

Answer 2

Given :-

Volume of Cylinder = 700 cm³

Area of base (Circle) = 100 cm²

To Find :-

Height (h) of Cylinder

Solution :-

We know that,

Volume of Cylinder = πr²h = 700

Area of base = πr² = 100

So ,

➮ πr²h = 700

➮ 100(h) = 700. ---(πr² = 100cm²)

➮ h = 700/100

➮ h = 7 cm

Hence ,

Height (h) of Cylinder is 7cm.✅
