Answer:
7 cm
Step-by-step explanation:
You want the radius of a cylinder with a total surface area of 1188 cm² and a radius plus height of 27 cm.
Surface area
The total surface area of a cylinder is ...
A = 2πr(r +h)
Filling in the given values, we get ...
1188 cm² = 2πr(27 cm)
r = 1188/(54π) cm = 7.00 cm
The radius of the base is 7 cm.
