Find the volume and surface area of the following sphere. Round your answers to the nearest tenth $(\text{Take} \pi =3.14)$.

Copy and complete the table, assuming that each set of measurements are for a sphere. Round all values to the nearest tenths.

During a severe drought in southern California, the city of Los Angeles used small black spheres to try to reduce the amount of water that evaporated from its reservoirs. About $96$ million black spheres, each measuring $10 \mathrm{cm}$ in diameter, were released into the Los Angeles Reservoir in an attempt to block the sunlight. The shade balls reduced evaporation by $85$ to $90$ percent, saving over $1$ trillion liters of water per year.

Interestingly enough, the balls were filled with water so that they would not blow away. What volume of water was in all of the balls in the Los Angeles Reservoir? Show your working. Round all values to the nearest tenths. $\left(\text{Take} \mathrm{\pi }=3.14\right)$

Find the volume of the following shape. $\left(\text{Take} \mathrm{\pi }=3.14\right)$

Find the volume of the following shape. $\left(\text{Take} \mathrm{\pi }=3.14\right)$

Find the volume of the following shape. $\left(\text{Take} \mathrm{\pi }=3.14\right)$

A soccer ball is packaged in a cubic box with side lengths of $22 \mathrm{cm}$. Assuming that the ball touches all faces of the box, what percentage of the box is wasted space. Round all values to the nearest tenths. $\left(\text{Take} \mathrm{\pi }=3.14\right)$

Find the radius of a sphere that has an equal surface area and volume.
