The area of the sector AOB is 487 and mZAOB = 270 degrees.
Find the radius of Circle O:

Radius of circle = 14.38 unit (Approx.)

Explanation:

Given:

Area of the sector AOB = 487 unit²

Angle of sector AOB = 270°

Find:

Radius of circle

Computation:

Area of the sector = [θ/360][πr²]

Area of the sector AOB = [θ/360][πr²]

487 = [270/360][(3.14)r²]

487 = [0.75][(3.14)r²]

487 = [2.355r²]

r² = 487 / 2.355

r² = 206.80

r = 14.38

Radius of circle = 14.38 unit (Approx.)

is the art and science of cultivating the soil, growing crops and raising livestock. it includes the preparation of plant and animal products for people to use and their distribution to markets.

agriculture provides most of the world’s food and fabrics. cotton, wool, and leather are all agricultural products. agriculture also provides wood for construction and paper products.
