The surface area of the right cylinder is 188 sq. units. The correct option is A. 188 sq. units
What is the surface area of a cylinder?
From the question, we are to determine the surface area of the given right cylinder.
The total surface area of a cylinder can be calculated by using the formula,
TSA = 2πr(r + h)
Where TSA is the total surface area
r is the radius, h is the height
From the given information,
r = 3
h = 7
Putting the parameters into the formula, we get
TSA = 2πr(r + h)
TSA = 2π×3(7 + 10)
TSA = 6π × 10
TSA = 60π sq. units
TSA = 188.4 sq. units
TSA ≅ 188 sq. units
Hence, the surface area of the right cylinder is 188 sq. units. The correct option is A. 188 sq. units
