Answer:
See below
Step-by-step explanation:
Using PEDMAS:
O Subtract 12 from the product of 5 and 3, then multiply by 87
So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
