Question

The diagram shows a cylindrical chocolate

box having radius 2.5 cm and height 10 cm .
Calculate the curved surface area
of the chocolate
box.

Answer 1

157.1cm^2

Explanation:

Given data

Radius=2.5cm

Height= 10cm

The expression for the curve surface area of cylinder

Area of the curved surface = 2πr × h

Substitute

=2*3.142*2.5*10

=157.1cm^2

Hence the answer is 157.1cm^2
