a. Calculate the circumference of the entire figure
b. Show with a calculation that the area of the triangle is 62,4 cm6^2
c. Calculate the area of the entire figure
Thanks!!
+128470 a. We have three half-circles each with a radius of 6
So....the total crcumference is
3 (1/2) * 2 * pi (6) = 18 pi cm ≈ 56.55 cm
b. This is an equilateral triangle with sides of 12
Its area is
(1/2)12^2* √3/2 = 144√3/4 = 36√3 cm^2 ≈ 62.35 cm ^2 (1)
c. The total area of the three half-circles is
3 (1/2) * pi (6)^2 = 54 pi cm^2 ≈ 169.65 cm^2 (2)
So....the approximate area is (1) + (2) ≈ 232 cm^2
