Question

the curved surface area of a right circular cylinder of height 14 cm is 88 CM square find the diameter of the base of the cylinder ​

Answer 1

Answer:

Given , The height of cylinder =14cm

and , the curved surface area of cylinder =88cm

2

we know that ,

the curved surface area of cylinder =2πrh

and 2r=d

here , r=radius of cylinder , d=diameter of cylinder and h=height of cylinder

so , the curved surface area of cylinder =πdh =88cm

2

π×d×14=88

22/7×d×14=88

d=2cm

so, the diameter of the cylinder is 2 cm

mark me brainliest if it was useful

Answer 2

Answer:

Height (h) of cylinder = 14 cm

& radius of cylinder ber

Given

Curved surface area of cylinder = 88 cm²

21rh = 88 cm²

2 × 22/7 × r × 14 cm = 88

r = 88 x 7 / 2 × 22 × 14

r = 1 cm

Diameter = 2 x Radius = 2x1=2 cm

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