Question

I have a math question that I’m not really experienced in. Please just tell me how to find the answer, don’t give me the answer but show me the process. This way it helps me understand.

A cylindrical-shaped container is to be painted. It has diameter of 5.3cm and height of 12cm. Calculate the surface area to be painted.

Answer 1

The answer is 243.93
`cm^(2)`, just in case you want to check.

Explanation:

SA=2πrh +2π
`r^(2)`

r = 2.65 cm radius is half the diameter. r=d/2

h= 12 cm

SA= 2π(2.65 cm)(12 cm) + 2π (2.65 cm)^2
