Question

Two squares are attached to the sides of a quarter circle as shown.

What is the best approximation for the area of this figure?

Use 3.14 to approximate pi.

178.5 mm²

215.7 mm²

231.8 mm²

278.5 mm²

Answer 1

278.5 I TOOK THE TEST

Explanation:

Answer 2

Area of a square is ; 10 * 10 = 100
We have 2 squares so total is 200.

Area of a circle is pi* r^2 = 3.14 * 100 = 314
But we have quarter of a circle so area will be 314/4 = 78.5

Total area of the shape is 200 + 78.5 = 278.5
