Question

The radius of a circle is 1 mlle, What is the circle's area?

Answer 1

Answer:

area = 3.14 mi² (to the nearest hundredth)

Step-by-step explanation:

Area of a circle = $\pi r^2$

(where r is the radius)

Given:

• radius = 1 mile

Substitute r = 1 into the equation:

⇒ area = $\pi$ × 1²

⇒ area = $\pi$ mi²

⇒ area = 3.14 mi² (to the nearest hundredth)

Answer 2

Answer:

π

Step-by-step explanation:

→ State the formula for the area of a circle

π × r²

→ Substitute in the numbers

π × 1² = π
