Given:
h = 20
r = 5
Determine the surface area of the right cylinder.
Formula for the surface area of the right cylinder:
TSA = =2πrh+2πr^2
Solution:
Substitute the given values of h and r to the formula for the total surface area of the right cylinder.
TSA = 2πrh+2πr^2
TSA = 2π(20)(5)+2π(5)^2
TSA = 200π+50π
TSA = 250π
TSA = 785.4 square units
Final answer:
TSA = 785.4 square units
