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
