Answer:
π
Explanation:
→ State the formula for the area of a circle
π × r²
→ Substitute in the numbers
π × 1² = π
area = 3.14 mi² (to the nearest hundredth)
Area of a circle =
(where r is the radius)
Given:
Substitute r = 1 into the equation:
⇒ area = × 1²
⇒ area = mi²
⇒ area = 3.14 mi² (to the nearest hundredth)
