Answer:
volume of cylinder = 13895.7 cm³ C.S.A. of cylinder =2289.25 cm²
Step-by-step explanation: given circumference of the circle = 76.35 cm
height = 30 cm
Radius of the cylinder
circumference = 2πr
76.35 = 2 × 22/7 × r
76.35 × 1/2 × 7/22 = r
12.14 cm = r
r = 12.14 cm
⇒ volume of the cylinder
= πr²h
= 22/7 × 12.14 × 12.14 × 30
= 13895.7 cm²
⇒C.S.A of the cylinder
= 2πrh
= 2 × 22/7 × 12.14 × 30
= 2289.25 cm²
