Question

Paisley and her dad are digging a pond in their yard. They know the diameter will be 50 yards. What will the area of the pond be?

pls help i need soon will give brain liest if right

Answer 1

See step-by-step, as it depends which value of pi you use.

Explanation:

Equations

• Diameter =
  `2r`
• Area of a circle =
  `\pi r^2` (where r is the radius)

Assuming the pond is circular...

Diameter of pond = 50 yd ⇒ r = 50 ÷ 2 = 25 yd

Substitute r = 25 into the equation for the area of a circle:

`\implies A= \pi *25^2=625\pi` yd²

Using
`\pi =3.14`, area = 1962.5 yd²

Using
`\pi=(22)/(7)`, area = 1964.3 yd² (nearest tenth)

Using
`\pi`, area = 1963.5 yd² (nearest tenth)
