Circumference = 10π in, Area = 25π in²
Circumference = 19 π in, Area = 90. 25 π in²
Area = 225 π in²
Circumference = 16π
How to determine the circumference and area
It is important to note that the formula for area and circumference are;
Area = πr^2
Circumference = 2πr
For the first column, we have
radius = 5in
Substitute the values of the radius into the formula
Circumference = 2 × π × 5
Circumference = 10π in
The area;
Area = π × 5 × 5
Area = 25π in²
For the second column,
radius = 9. 5 in
Substitute the values of the radius into the formula
Circumference = 2 × π × 9. 5
Circumference = 19 π in
Area = π × 9. 5 × 9. 5
Area = 90. 25 π in²
For the third column
radius = 15in
Substitute the values of the radius into the formula
Area = π × 15 × 15
Area = 225 π in²
For the fourth column
radius = 8 in
Substitute the values of the radius into the formula
Circumference = 2 × π × 8
Circumference = 16π
From the solved solution, we can see that the shape is a circle.
