Find the volume of a cylinder with radius of base 7 cm and height 10.2 cm. (Use π=)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1570.8 cm3 .
Volume of cylinder = π × r2 × h
Radius r = 7 cm
Height h = 10.2 cm
π = 22/7
Volume = (22/7) × 7 × 7 × 10.2
= 22 × 7 × 10.2
= 1570.8 cm3
