Question

Which equation can be used to find the surface area of the cylinder? A cylinder with a radius of 4 inches and height of 16 inches. S = 2 pi (4) squared + 2 pi (4) (16) S = 2 pi (8) squared + 2 pi (8) (16) S = 2 pi (16) squared + 2 pi (16) (4) S = 2 (4) squared + 2 (4) (16)

Answer 1

S = 2π(4)(16) + 2π(4²)

So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)

Explanation:

Hope this help and please stay safe thank you

Answer 2

S = 2π(4)(16) + 2π(4²)

So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)

Explanation:

The formula for total surface area of a cylinder is;

Total surface Area; S = 2πrh + 2πr²

Now,we are given;

Height;h =16 inches

Radius;r = 4 inches

Thus, plugging in the values into the Area formula, we have;

S = 2π(4)(16) + 2π(4²)

The correct answer from the options given is;

S = 2 pi (4) squared + 2 pi (4) (16)
