pls help i need soon will give brain liest if right

Answer 1

Answer:

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

Step-by-step 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:

$\implies A= \pi \times25^2=625\pi$ yd²

Using $\pi =3.14$, area = 1962.5 yd²

Using $\pi=\dfrac{22}{7}$, area = 1964.3 yd² (nearest tenth)

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