Question

3. Find the volume of the cylinder given the circum-
ference of the base is 176cm and height 30cm.

answer written send ​

Answer 1

Answer:

circumference=176cm

r=d/2

r=176/2=88cm

h=30cm

volume of cylinder=πr^2h

,volume of cylinder=22/7×88×88×30

volume of cylinder=511040/7

volume of cylinder=730148.57142857

Answer 2

Answer:

Height of Cylinder =30 cm

Circumference of the base = 176 cm

So.

2πr = 176.

2×22÷7×r = 176 cm

44÷7 ×r = 176 cm

r = 176 ×7 ÷44

r = 4×7

r = 28 cm

Now

Radius of the Cylinder = 28 cm

Volume of the Cylinder = πr^2h

= 22÷7× 28 ×28 ×30

= 22×4 ×28×30

= 88× 840

= 73920 cm^3
