Answer 1

Step-by-step explanation:

Curved surface area of cylinder = 2πrh .

In the question ❓.

• diameter ❓
• area = 88cm sq.
• height = 14 cm.

2× 22/7 × r × 14 = 88

88 r = 88

r = 1

diameter = 2 cm.

I hope it's helpful for all of you.

Answer 2

Answer:

Daimeter = 2cm.

Step-by-step explanation:

$curved \: surface \: area \: = 88cm \\ height = 14cm \\ \\ \\ csa = 88 \\ 2 \pi \: rh = 88 \\ 2 \times 22 \div 7 \times r \times 14 = 88 \\ r = 88 \times 7 \div 2 \times 22 \times 14 \\ r = 1 \\ \\ so \: radius \: of \: the \: cylinder \: is \: 1cm. \\ and \: diameter \: is \: 2cm.$

HOPE IT HELP YOU....!!!!!
