A flying disc has a diameter of 14 inches. What is the approximate area of the disc?

2
a. 44 in
2
b. 88 in
2
c. 154 in
2
d. 616 in
(with explanation)

C. 154 in

Step-by-step explanation:

The radius of any circle is 1/2d (d is the diameter). So, our radius here is

r = 1/2(14)

r = 7

The area of a circle is A = (pi)(r^2)

We can approximate pi=3.14 and plug in everything we know to solve

A = (pi)(r^2)

A = (3.14)(7^2)

A = (3.14)(49)

A = 153.86

We can round that to 154 and that's your answer

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
