Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
Answer: Area = 63.9 inches²
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle
π is a constant whose value is 3.14
From the information given,
circumference = 28.3 inches
Therefore,
28.3 = 2 × 3.14 × r
28.3 = 6.28r
r = 28.3/6.28
r = 4.51 inches
The formula for determining the area of a circle is expressed as
Area = πr²
Area = 3.14 × 4.51² = 63.9 inches²
