A cylindrical cake with a height of 5 inches has a 30 degree slice removed. If the volume of the removed slice is 40 inches what
sesenic [268]

Answer: 5.52\ in.

Step-by-step explanation:

Given

Height of cylindrical cake is h=5\ in.

30^{\circ} slice is removed

Volume of the slice is V=40\ in.^3

Area of slice is

\Rightarrow \dfrac{30^{\circ}}{360^{\circ}}\times \pi r^2\\\\\Rightarrow \dfrac{\pi r^2}{12}

Volume of slice will be multiplication of area and height

\Rightarrow V=A\times h\\\\\Rightarrow 40=\dfrac{\pi r^2}{12}\times 5\\\\\Rightarrow \pi r^2=\dfrac{40\times 12}{5}\\\\\Rightarrow r^2=\dfrac{40\times 12}{3.142\times 5}\\\\\Rightarrow r^2=30.55\\\Rightarrow r=5.52\ in.

Hence, the radius of the cake is 5.52\ in.
