Q. What is the volume of a sphere with a diameter of 48.6ft, rounded to the nearest tenth of a cubic foot?Answer: ft3
Find Radius: To find the volume of a sphere, we use the formula V=34πr3, where r is the radius of the sphere. Since the diameter is given, we first need to find the radius by dividing the diameter by 2.Radius r = Diameter / 2 = 248.6 ft
Calculate Radius: Now, let's calculate the radius. r=248.6ft=24.3ft
Substitute and Calculate Volume: Next, we will substitute the radius into the volume formula and calculate the volume.V=34π(24.3ft)3
Calculate Volume with Radius: Let's calculate the volume using the radius we found.V=34π(24.3ft)3=34π(24.3ft×24.3ft×24.3ft)
Perform Radius Cubed Multiplication: Now, we perform the multiplication for the radius cubed.(24.3ft)3=24.3ft×24.3ft×24.3ft=14367.87ft3
Multiply by (34)π: We then multiply this result by (34)π to get the volume.V=(34)π×14367.87ft3
Calculate Numerical Value: Now, we calculate the numerical value for the volume. V≈(34)×3.14159×14367.87 ft3≈4.18879×14367.87 ft3≈60194.217 ft3
Round to Nearest Tenth: Finally, we round the volume to the nearest tenth of a cubic foot as asked in the question prompt. V≈60194.2 ft3
