Question

right circular cylinder has base diameter
14 cm and height
28 cm - find its curved
surface area.​

Answer 1

Answer:

2cm

Step-by-step explanation:

Height (h) of cylinder = 14cm

Let the diameter of cylinder be d.

Curved Surface Area of Cylinder = 88cm square

2πrh = 88 cm square

π dh = 88 cm square. (d = 2r)

22/7 × d × 14 = 88 cm

d = 2 cm

Therefore,the diameter of the base of the cylinder is 2 cm

Answer 2

Answer:

the curved surface area will be 1,232cm.

Step-by-step explanation:

the diameter of right circular cylinder =14 cm.

R= d/2

R = 14/2

R = 7

and the height of right circular cylinder = 28 cm

A to Q

Curved surface area = 2πrh

= 2× 22/7 ×7×48

= 2×22× 28

= 1,232cm

hope it helps you.
