The formula for the surface area of a cylinder is SA=2πr(h+r)
. What is the value of SA
when r=3
centimeters and h=4
centimeters?
To find the value of SA when r=3 cm and h=4 cm, plug in these values into the formula:
SA = 2π(3)(4+3)
SA = 2π(3)(7)
SA = 2π(21)
SA = 42π
So, the value of SA when r=3 cm and h=4 cm is 42π square centimeters.
