A Hemispherical Tank with a Radius Of $3.50 \mathrm{~m}$ Is Full of Water

Short Answer

A hemispherical tank with a radius of $3.50 \mathrm{~m}$ is full of water. Find the work needed to pump the water to a height $1.50 \mathrm{~m}$ above the top of the tank. Recall that the mass density of water is $1000 \mathrm{~kg} / \mathrm{m}^{3}$ and that gravity is taken to be $9.81 \mathrm{~m} / \mathrm{s}^{2}$ . Use three significant digits.
