Full solution

Q. What is the volume of a sphere with a radius of 37.5 m 37.5 \mathrm{~m} , rounded to the nearest tenth of a cubic meter?\newlineAnswer: m3 \mathrm{m}^{3}
  1. Recall Sphere Volume Formula: Recall the formula for the volume of a sphere. The formula for the volume of a sphere is V=43πr3V = \frac{4}{3}\pi r^3, where VV is the volume and rr is the radius of the sphere.
  2. Substitute Given Radius: Substitute the given radius into the formula.\newlineRadius r=37.5mr = 37.5\,\text{m}\newlineVolume V=43π(37.5)3V = \frac{4}{3}\pi(37.5)^3
  3. Calculate Volume: Calculate the volume using the given radius.\newlineV=43π(37.5)3V = \frac{4}{3}\pi(37.5)^3\newlineV=43π(140625)V = \frac{4}{3}\pi(140625)\newlineV=43×π×140625V = \frac{4}{3} \times \pi \times 140625\newlineV43×3.14159×140625V \approx \frac{4}{3} \times 3.14159 \times 140625\newlineV4×3.14159×46875V \approx 4 \times 3.14159 \times 46875\newlineV12.56636×46875V \approx 12.56636 \times 46875\newlineV588,785.25 cubic metersV \approx 588,785.25 \text{ cubic meters}
  4. Round to Nearest Tenth: Round the volume to the nearest tenth of a cubic meter. V588,785.3m3V \approx 588,785.3 \, \text{m}^3
