Question

answer the question.......

Answer 1

Answer:

38.5cm²

Step-by-step explanation:

base circumference=11

2πr=11

44/7r=11

r=77/44

r=7/4

volume=π*r²*h

v=22/7×7/4×7/4×4

v=38.5cm²

Answer 2

clearly, the length of the given rectangle is the perimeter of the base of the given cylinder and breadth of the rectangle is the height of the cylinder.

height =4cm.
h=4cm
let r be the radius of it's base .
then,2πr= 11cm
2×22/7×r = 11 cm
r= 11×7/44
r=77/44
r=7/4cm

volume of the cylinder =πr^2h cubic unit
=22/7×7/4×7/4×4
= 11×7/2
= 77/2
=38.5cm^3

hence, the volume of the cylinder is 38.5 cm^3.
