Answer:
145 each because the total 'area' of a circle is 360 like a square. 35+35 is 70. 360-70=290/2

Answer:
(x - 2)² + (y + 8)² = 121
Step-by-step explanation:
circle: (x – h)² + (y – k)² = r² (h , k) center r: radius
h = 2 k = - 8 r = 11
equation: (x - 2)² + (y + 8)² = 121
The area of an equilateral triangle is (1/2)bh. The base is 5, so using the Pythagorean theorem we get h by:
5² = (5/2)² +h²
h = √18.75
h = 4.33
So the area of one face is (1/2)(5)(4.33) = 10.825m²
The total area is 4(10.825m²) = 43.3m²
