What is the volume of a cylinder if the radius of the cylinder is $10 ext{ cm}$ and height is $20 ext{ cm}$? (Take $\pi = 3.14$)

Question

What is the volume of a cylinder if the radius of the cylinder is $10 	ext{ cm}$ and height is $20 	ext{ cm}$? (Take $\pi = 3.14$)

Accepted Answer

**Solution:**

1. The formula for the volume of a cylinder is:
   $$V = \pi r^2 h$$

2. Given:
   - Radius, $r = 10 	ext{ cm}$
   - Height, $h = 20 	ext{ cm}$
   - $\pi = 3.14$

3. Substitute the values into the formula:
   $$V = 3.14 	imes (10)^2 	imes 20$$

4. Calculate the square of the radius:
   $$10^2 = 100$$

5. Multiply all values:
   $$V = 3.14 	imes 100 	imes 20 = 314 	imes 20 = 6280$$

6. Therefore, the volume of the cylinder is:
   $$6280 	ext{ cm}^3$$

**Answer:** $6280 	ext{ cm}^3$
