Answer:

A: The scale is 40. (not sure how you word it, the drawing is 40 times smaller)

B: 60 inches.

C: 200 ft.

Step-by-step explanation:

A: if the hight is 9 inches in the drawing, and 30 ft in real life, you can change the ft in to inches. ( 30 x 12) and divide that by 9 to find how much different the size is from the drawing to real life. This will give you the equation 360 divided by 9. Thus the answer is 40.

B: Just solving perimeter. L + L + W + W. In this case, (21 + 21 + 9 + 9 = 60)

C: As determined previously, the drawing is 40 times smaller than the real screen so the drawing times 40 will give the real thing in inches. To make this simpler you can change the 60 inches to 5 feet. The equation would be (5 x 40) The answer being 200.

What is the approximate surface area of the sphere 15yd?
tekilochka [14]
<span>The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15x15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards.</span>
