Question

A circle has a radius of 7.2 feet and a central angle aob that measures 112°. what is the area of sector aob? use 3.14 for pi and round your answer to the nearest tenth.

Answer 1

The area of the sector will be given by:
A=θ/360πr²
but
θ=112°, r=7.2 ft, π=3.14
hence
A=112/360×3.14×7.2²
A=50.64192 ft²
A~50.6 ft²
