Answer:
5544 square units
Step-by-step explanation:
Translation does not change the dimensions of the figure. The two figures together tell you the right triangle has a base of 154 units and a height of 72 units.
The area of a triangle is given by ...
A = 1/2bh
A = 1/2(154 units)(72 units) = 5544 square units
The areas of each of the triangles are 5544 square units.
BG = 40. Equation: 4(3) + 8 + 20 = 40.
The
solution would be like this for this specific problem:
729 = 4*pi * r^3/3
<span>
Multiply both sides by 3 </span>
<span>2185 = 4*pi*r3</span>
<span>Divide both sides by 4 pi.</span>
<span><span>173.9649681528662 = r3
r = </span>5.58239548</span>
A = 4 pi r^2
<span>A = 4 * 3.14 * 5.582395482</span>
<span>
A = 391.7 square inches</span>
The
surface area of the sphere to the nearest tenth of an inch is 391.7
square inches.
