Answer:
C. 453.16 m²
Step-by-step explanation:
The formula for finding the area of a circle is A=πr² (area equals pi times the radius squared)
First, we need to get the radius of the circle by simply dividing it's diameter by 2
24 m ÷ 2 = 12 m
Second, we use the formula A=πr²
A=πr²
A=π(12 m)² - We multiply 12 into itself, which is
12×12=144
Then we multiply π by 144 (the value of π is approximately 3.14)
A=3.14 × 144 = 452.16m² - this is now the area of the circular lagoon that has a diameter of 24 m
