Shelton Drew a circle with a radius ir 10 centimeters. He than shaded 2 portions of his circle. Find the area of the shaded port

Anton [14]

Answer:

The Area of shaded portion is 314000 cm²

Step-by-step explanation:

Given as :

The circle is drawn with radius = r = 10 cm

Two portion of circle is shaded

∵ two portion is shaded means whole the circle is shaded now

Let The area of shaded portion = A = area of circle

∵ Area of circle = A = π × radius²

where π = 3.14

Or, A = 3.14 × r²

Or, A = 3.14 × (100)²

Or, A = 3.14 × 10000

Or, A = $\dfrac{3140000}{100}$

I.e A = 314000 cm²

So, The Area of shaded portion = A = 314000 cm²

Hence, The Area of shaded portion is 314000 cm² Answer
