Area of semicircle: A = 1/2πr² A = 1/2π(10)² A = 1/2(100π) A = 157.0796327 Area of square: A = s²√3 / 4 A =10²√3 / 4 A = 43.30127019 Area of Shaded region = Area of semicircle + area of square = 157.07~~ + 43.30.. = 200.38 cm² approximately
AB is the diameter of the half-circle. The radius is ½ of AB Also, I do not see a square. I see an equilateral triangle, with sides all equal to 10
i mean.. triangle.. wrong word.
@phi my answer isn't correct for you?
I'll just replace all radius with 5.. and everything will be correct right?
yes, you have the right idea... but the radius is 5 (not 10). The area of the triangle is ok.
thank you so much :)
