The radius of a circle measures 7 inches. A central angle of the circle measuring 4π/15 radians cuts off a sector. What is the area of the sector? Enter your answer, as a simplified fraction, in the box.

Step-by-step explanation:

Radius = 7 inches

Angle of sector = 4pi/15

convert to degree = 4pi/15 × 180/pi = 48°

Area of sector = angle of sector/ angle of circle × pi × r²

= 48/360 × 22/7 ×7²

= 20 ⁸/15 inches²

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
