10.275 ∪m

Explanation:

To find the surface area of mitochondria, therefore, is the sum of the surface area of a cylinder and 2 half-spheres (the two caps) (-which is similar to one sphere).

The surface area of lateral sides of the cylinder = 2πr*h = 2 x 3.142 x 0.57 x 2.2 = 6.192

The surface area of sphere = 4πr² = 4 x 3.142 x (0.57) ² = 4.083

Total surface area = 6.192 + 4.083 = 10.275
