Diameter = 14cm so radius = 7cm. Height = 5cm. Take pi as 22/7 Volume of a cylinder = pi*radius2*height Volume = 22/7*72*5 = 770 cubic cm.

Circumference = 2*pi*radius or pi*diameter Circumference = 87.9645943 or 88 cm to the nearest cm

Area is 98cm2

A = 615.75 cm2

A = 615.75 cm2

The question cannot be answered. There is no information on what aspect of the cylinder is 14 cm: the radius, diameter, circumference, height.

First we must find the radius: Curved surface area of the cylinder excluding the two end pieces = 88 cm2 2*pi*radius*14 = 88 Divide both sides by 2*pi*14 radius = 1.000402499 cm Volume = pi*1.0004024992*14 Volume = 44.01770994 cubic cm

The diameter is 28cm

14cm

You are not finding the area you are finding the volume. The answers is 1232 cm3

The diameter would be 28 cm.

The circumference and radius of the circle are:C = 44 cmr = 7 cm
