Question

the volume of cylinder is 38500 cm cube if the height of the cylinder is 40 cm find the diameter of its base

Answer 1

volume of cylinder=πrh

volume of cylinder=22/7×r×40

38500=22/7×r×40

r=38500×7/22×40

r=38500×7/880

r=3850×7/88

r=3o6.25

diameter= 2r

diameter=2×306.25

diameter=612.5

Answer 2

Answer:17.5 cm

Step-by-step explanation:

Volume of cylinder = 38500 cm³

Height of cylinder = 40 cm

Now,

Volume of cylinder = πr²h

38500 = 22/7 x r² x 40

r² = (38500 x 7)/ (40 x 22)

r² = 1925 x 7/44

r² = 13475/44 = 306.25

r = √306.25 = 17.5 cm
