Question

A balloon has a radius of 7.25 cm. What is the approximate area of the circle, rounded to the nearest whole number?

Answer 1

165 square cm

Explanation:

Area of a circle is
`\pi r^2`, where r = radius. We're given the radius as 7.25.

• 
  `3.14 * 7.25^2`
• 
  `3.14 * 52.5625`
• 
  `165.04625`
• 165.04625 ≈ 165 square cm

Therefore, the answer is 165 square cm.
