Question

4 Find the area of the circle pictured above. Round your answer to the nearest tenth

Answer 1

The radius of the given circle is = 4

The general expression for the area of the circle is :

`\text{ Area of circle = }\pi(radius)^2`

Substitute the value if radius = 4 for the area of given circle;

`\begin{gathered} \text{ Area of circle = }\pi(radius)^2 \\ \text{ Area of circle = }\pi*4^2 \\ \text{ Area of circle = }3.14*16 \\ \text{Area of circle = }50.24 \end{gathered}`

to cenvert them into nearest tenth is :
