Question

Radius 11 cmFind the surface area to the nearest hundredthusing 3.14 instead of Pi.126.65 cm2138.16 cm21393.11 cm21519.76 cm2

Answer 1

The area of the circle is given by the formula

`A=\pi r^2`

where r is the radius here.

It is given r = 11.

Hence the area is given by

`\begin{gathered} A=\pi*11*11 \\ =3.14*11*11 \\ =379.94 \end{gathered}`
