Clayton wants to make a cylindrical case that will fit a bass drum with a height of 14 inches and a diameter of 24 inches. with is the surface area of the case? use 3.14 \pi

1. You can solve this problem and calculate the surface area of the case, by applying the formula for calculate the surface area of a cylinder, which is:

 A=2πr²+2πrh

 "A" is the surface area of the cylinder.
 "r" is the radius.
 "h" is the height of the cylinder (h=14 inches).

 2. You need to calculate the radius. So, you have:

 r=Diameter/2
 r=24 inches/2
 r=12 inches.

 3. You already have the height and the radius, so you can substitute these values into the formula (A=2πr²+2πrh) for calculate the surface area of the case:

 A=2πr²+2πrh
 A=2(3.14)(12 inches)²+2(3.14)(12 inches)(14 inches)
 A=904.32 inches²+1055.04 inches²
 A=1959.36 inches²

40%=2/550=1/230=3/1056=14/25
