9. Find the surface area of the cylinder. S.A. = 2πrh+2πr^2 Round to the nearest tenth.
The cylinder has a radis of 4 and Hight of 6
80 m^2
251.3 m^2
301.4 m^2
401.9 m^2
To find the surface area of the cylinder, we can use the formula S.A. = 2πrh + 2πr^2.
Given that the radius (r) is 4 and the height (h) is 6, we can plug these values into the formula.
S.A. = 2π(4)(6) + 2π(4^2)
S.A. = 48π + 32π
S.A. = 80π
When rounded to the nearest tenth, the surface area of the cylinder is approximately 251.3 m^2.
So the correct answer is 251.3 m^2.
