Question

The area of the centre circle on a football pitch is 265 m(squared). Calculate the radius of the circle to the nearest 0.1 m. Someone please help

Answer 1

\[Area = \pi r^2 \]
\[265 = \pi r^2 \]
\(\pi\) can be 3.14
\[265 = 3.14 r^2 \]

divide both sides by 3.14 and then find the square root of the quotient to find the radius
