Question

A pie dish with circular cross sections is 24 cm across the top, 16 cm across the bottom and 6 cm deep. Find the volume of the dish.

Answer 1

You could use the equation of the straight line passing through the points (0, 8) and (6, 12). Then evaluate:
\[\pi\times\int_{0}^{6}(expression)^2\]

Answer 2

\[v=\left(\frac{1}{3}\right)(a+b)+h\sqrt{a b} \]for a= 24, b=16 and h= 6\[v=\frac{40}{3}+48 \sqrt{6}=130.9 \]

Answer 3

The pie dish is a Frustum of a Cone.

Answer 4

Sorry. My answer is incorrect. Used the diameters as radii. Thank you @ ryryfoeshow
