Question

A circle with raidius 10 has a sector with a central angle of 2/5π raidians

Answer 1

Answer:

Area of the sector = 62.86 unit²

Step-by-step explanation:

Given:

Radius = 10 unit

Central angle = 2/5π radians

Find:

Area of the sector = ?

Computation:

$Area =\frac{1}{2}r^2 \theta\\\\ Area =\frac{1}{2}(10)^2(\frac{2 \pi}{5} )\\\\Area =\frac{1}{2}(100)(1.257)\\\\Area =62.86$

Area of the sector = 62.86 unit²
