Question

Evan is painting a stool that has a cylindrical seat and four rectangular prism legs. The seat has a diameter of 14 inches and a height of 4 inches. Each leg is 4 inches by 4 inches by 18 inches. How much area will Evan have to paint? Use 3.14 for TT. Show your work.

Answer 1

Do you have an answer that you need to check or do you need me to go through the steps?

Answer 2

Can u go through the steps! I didn't know I missed 2 questions and i don't get them :S

Answer 3

Area of the top of the stool:

A = pi*r^2

A = (3.14)*(7)^2 ... The diameter is 14 in, so the radius is 14/2 = 7 in

A = 153.86 square inches

-----------------------------------

Lateral surface area of the top of the stool

A = 2pi*r*h

A = 2*(3.14)*7*4

A = 175.84 square inches


-------------------------------------

Surface area of one rectangular prism leg (ignoring the top face)

SA = 2*(LW+WH+LH) - LW

SA = 2*(4*4+4*18+4*18) - 4*4

SA = 2*(4*4+4*18+4*18) - 4*4

SA = 304

There are 4 of these legs. So the total surface area of the legs is 4*304 = 1216 square inches.

--------------------------------------


Now add up the area of the top, the sides of the stool, and the legs of the stool to get


153.86 + 175.84 + 304 = 633.7


So Evan will have to paint 633.7 square inches total.
