Question

find the area of sector whose are length and radius are 20cm and 8cm respectively ​

Answer 1

Answer:

80 cm²

Step-by-step explanation:

Find the circumference:

Circumference = 2πr

Circumference = 2π(8) = 16π cm

Find the area:

Area = πr²

Area = π(8)² = 64π  cm²

Find the area of the sector:

Arc Length = 20 cm

Area of the sector = ( arc length / Circumference ) x Area

Area of the sector = (20/16π) 64π = 80 cm²

The area of the sector is 80 cm²
