The total surface area of a sphere is 3850 CM square find the
2020年2月18日 · The total surface area of a sphere is 3850cm^2. To find the diameter of the sphere. The total surface area of a sphere = 4πr^2. 3850 cm^2 = 4×22/7 × r^2. 3850 cm^2 = 88/7 × r^2. 43.75 cm^2 = r^2 / 7. 43.75 × 7 = r^2. 306.25 = r^2. 17.5 = r ^2. diameter = 2× radius . Diameter = 2×17.5. Diameter = 35 cm. Hence. Diameter of the sphere is 35 ...
