Hello there! The formula for finding the area of a circle is π * r². The radius is 1/2 of the diameter. The diameter is 92 meters ½ of 92 is 46. So we will raise 46 to the second power. 46² is 2,116. Now, let's multiply that by 3.14 to ffind the area of the circle. 2,116 * 3.14 is 6,644.24. There. The area of the ice skating rink is 6,644.24 square feet.

bro.. i don't think someone is gonna answer all this for you, you should like figure this out on ur own..
Answer:
56.8 m²
Step-by-step explanation:
This shape is clearly a trapezium / trapezoid. So :
Area of a trapezium is given by the formula :

Substitute values given in diagram :
a = 4.2
b = 10
h = 8

7.1 × 8 = 56.8
Units will be m² as this is area
Giving us our final answer of 56.8 m²
