Question

If volume of cylinder is 900 square cm with height of 20 can then what is its diameter?​

Answer 1

Answer:

volume=900 sq.cm

height=20 cm

volume of cylinder=pi*r^2*h

900=22/7 * r^2 * 20

r=3.78

where r is the radius .

diameter=2 * radius=2 * 3.78 =7.56 cm

Answer 2

volume is in cubic units

Answer:

d=13.10794346257954cm

Step by step explanation:

given,

volume=900cubic cm

height=20cm

volume=1/3πr^2h

900=1/3×22/7×r^2×20

900=1/3×22/7×r^2×20

r^2=(900×3×7)/(22×20)

r^2=18900/440

r^2=1890/44

r^2=42.95454545454545

r=√42.95454545454545

r=6.553971731289772cm

d=r×2

d=6.553971731289772cm×2

d=13.10794346257954cm
