Question

A circle is cut into congruent sections and arranged to form a figure that approximates a parallelogram. Find the approximate height of the

figure when its area is 72.257 square centimeters

Answer 1

8.5cm

Explanation:

The shape is a circle which was cut into congruent sections.

The approximate height of the parallelogram is the radius of the circle which was cut.

Area
`=72.25\pi cm^2`

Area of a circle =
`\pi r^2`

Therefore:

`\pi r^2=72.25\pi \\r^2=72.25\\r=√(72.25)\\r=8.5 cm\\$The approximate height of the figure is 8.5cm`
