Answer:

Step-by-step explanation:
The area (A) of the sector is calculated using the formula
A = area of circle × fraction of circle
let x be the measure of the central angle, then
A = πr² ×
← substitute values
5π = π × 10² × 
5π = 100π ×
(cancel 50π and 2π )
5π = 50x ( divide both sides by 50 )
x =
=
← central angle
