Rozyta Tensubam 2 years ago

The surface area of the sphere = 154 cm² The surface area of the sphere of radius r, SA = 4πr² Then, SA = 4πr² = 154 cm² = r² = 154/4π = (154/4)(7/22) = (154×7)/(4×22) = r² = 49/4 = r = (7/2) = r = 3.5 cm. Thus, the radius of the sphere whose surface area is 154 cm² is 3.5 cm.
