The radius of a sphere is 22 millimeters. Find its surface area in square centimeters. Round your answer to the nearest hundredth (two decimal places). Use 3.14 to approximate pi.

Surface area = 4πr² = 4 * 3.14 * 22² = 6082.12

5.25 cm²

Step-by-step explanation:

B represents the area of the triangular end.

B = bh ( b is the base and h the perpendicular height )

Here b = 28 mm = 2.8 cm ← note change from mm to cm ( divide by 10 )

and h = 3.75 cm , thus

B = × 2.8 × 3.75 = 1.4 × 3.75 = 5.25 cm²
