The volume of a right circular cylinder with its height equal to the radius is $25\frac{1}{7}$ cm$^3$. Find the height of the cylinder. (Use $\pi = \frac{22}{7}$)

Question

Accepted Answer

Step 1: Let height and radius of cylinder $= x$ cm. $V = \frac{176}{7}$ cm$^3$
Step 2: $\frac{22}{7} 	imes x^2 	imes x = \frac{176}{7}$
Step 3: $x^3 = 8 \Rightarrow x = 2$. Height of cylinder $= 2$ cm
