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 -
