Question

The height of a right circular cylinder is 5 cm and the area of its base is 36×3.14 cm square find the curved surface area of the cylinder

Answer 1

Answer:

Step-by-step explanation:-

Area of base = 36×3.14

πr²=36×3.14

3.14×r²=36×3.14

3.14 is cancelled both sides.

r²=36.

r=√36.

r=6cm.

CSA of cylinder=πrh.

=3.14×6cm×5cm.

=3.14×30cm².

=94.2cm².

Hence,CSA of the cylinder having height of 5cm and base area of 36×3.14cm² will be 94.2cm².
