Problem

A billiards table has a horizontal radius of measurement 8cm and a vertical radius of 5 cm. Calculate the area of the ellipse.(π = 3.14).

2

Step

Given that the horizontal radius (a) is and the vertical radius (b) is

8 cm and 5 cm

3

Formula

To calculate the area of an ellipse, you can use this simple formula: \$Area = π \times "horizontal radius" \times "vertical radius"\$

4

Step

Substitute the values into the formula.

\$"Area" = 3.14 \times 8 \times 5\$

Area = \$125.66 cm^2\$

5

Solution

So, the area of the ellipse is \$125.66 cm^2\$.
