Answer:
D
Step-by-step explanation:
Area of the square ( 5.1x5.1 ) added to
Area of one triangle ( 0.5x5.1x5.95 ) times 4 (because there are four triangles)
The formula for the area of a circle is a = <span>πr², r being the radius.
To tackle this problem, find the area of the square and then subtract the area if the circle:
Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314
Area of square - area of circle = 400 - 314 = 86 m²
Hope this helps!

if the circumference of the shield is 100.48inches, nits radius is 16 inches and the area of the front of the shield is about 803.84 square inches.
proof
circumference = 2x r x Pi implies r =circumference / 2Pi=100.48/2x3.14=16
area = Pi x r²=3.14 x 16²=804.84
