Answer:

The surface of orange is 36π square inches.

Step-by-step explanation:

Given :An orange with a 3'' radius.

We have to find the surface area of orange with radius 3 inches.

Since, the orange is in shape of sphere.

So,  Surface of area of orange is same as surface area of sphere.

We know,

Surface area of sphere = 4\pi r^2

Given : radius= 3 inches

Surface area of orange = 4\pi\cdot (3)^2

Surface area of orange = 4\pi\cdot 9=36\pi

Thus, The surface of orange is 36π square inches.

Set this up as a ratio putting inches on top and feet on bottom. Then your first ratio would be 1/25 since 1 inch is the same as 25 feet.  In between them goes an equals sign and the the other ratio has an x on top (because inches is what we are looking for) and the 1500 on the bottom. Cross multiply to solve for x:
1(1500) = x(25).  Divide both sides by 25 to get 60
