A semicircular plate with radius 9 m is submerged vertically in water so that the top is 1 m above the surface. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Round your answer to the nearest whole number. Use 9.8 m/s for the acceleration due to gravity. Recall that the mass density of water is 1000 kg/m2.) IN

**Problem Statement:**

A semicircular plate with a radius of 9 meters is submerged vertically in water such that the top is 1 meter above the surface. Express the hydrostatic force exerted against one side of the plate as an integral and evaluate it. (Round your answer to the nearest whole number). Use 9.8 m/s² for the acceleration due to gravity. Recall that the mass density of water is 1000 kg/m³.

**Equation:**

\[ 2\rho g \int_{0}^{1} ( \sqrt{81 - x^2} ) dx = N \]

**Diagram:**

The diagram accompanying this problem depicts a semicircular plate submerged in water. The plate's flat edge is horizontal and located 1 meter above the water surface. The shaded area indicates the water submerging the plate.
