A circular plate has circumference 18.2 inches. What is the area of this plate? Use 3.14 for pi.
1 answer:
Answer:
26.22in²
Step-by-step explanation:
First get the radius using the formula of a circumference.
C = 2πr = 18.2
2(3.14)r = 18.2
6.28r = 18.2
Divide both sides by 6.28 to get r
r = 2.89
Now get the area of a circle using the formula:
A = πr²
A = 3.14(2.89)²
A = 3.14(8.35)
A = 26.22in²

His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.
So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.
