To find the Area of the Shaded region:

☆Make a Formula of how to get it in your head.

= Area of Triangle - Area of Circle

Equilateral means all the sides are the same. Thus all. the sides are 10

☆Find Area of Triangle

Formula: Area of Triangle=

1,2(Base ×Height)

1,2(10×10)

100 ÷ 2 = 50 unit^2

☆Find Area of Circle

Assume: Radius of circle is 5

☆ Área of Circle= Pi × r^2

Pi × 5^2 = Pi × 25

Área of Circle = 78.5 (approximately)

Using Formula

Area of Triangle - Area of Circle

50 -
