Answer 1

Answer:

The formula of the volume of a cylinder is known as follow

V= πr²h

Where

π is 3,14 or 22/7.

d (diameter) is a straight line segment that crosses a center and connects two points on the circle.

r is the radius of the to part of the cylinder.

h is the height.

we can subsitute to our formula knowing that

d = 4cm (turn to r = 2cm,because the formula use r) ; h = 11cm

V = πr²h

= 3,14 × 2² × 11

= 3,14 × 4 × 11

= 3,14 × 44

= 138,16 rounded off (138,2cm3) result
