Question

the total surface area of a cylinder is 6512 centimetre square and the circumference of its base is 88 cm find its radius its volume​

Answer 1

Step-by-step explanation:

circumference = 2πr

= 2 × 22/7 × r = 88

= r = 88/2 * 7/22

= r = 138.2 cm

now tsa = 2πrh + 2π r×r = 6512

= 2*22/7*138.2*h+2*22/7*138.2*138.2=6512

then we will get h and the we can find the volume by applying the formula,V of cylinder = 2π r×r h

Answer 2

Step-by-step explanation:

6512 is right answer.
