Question

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

Answer 1

Area, A, of a circle is
\(A=\pi r^2\)
where \(\pi\) is approximately 3.1416, and r is the radius (two times the diameter)
area is measured in \(unit^2\)

The diameter of the given circle is 64mm.
Calculate the radius = diameter \(\div\)2 mm
The area should be in units squared, meaning \(mm^2\).
