Answer:
Explanation:
Since the outdoor ice skating arena is in the shape of a circle, we would determine its area by applying the formula for determining the area of a circle which is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle
From the information given,
Diameter = 42 feet
Radius = diameter/2 = 42/2 = 21 feet
Therefore,
Area = 3.14 × 21² = 1384.74 square feet
Rounding up to the nearest whole number, area of the outdoor ice skating arena would be 1385 square feet
