Utilizing the radius (r):
“`
Space = πr^2
“`
Utilizing the diameter (d):
“`
Space = (πd^2) / 4
“`
the place π (pi) is a mathematical fixed roughly equal to three.14159.
Instance:
Discover the world of a circle with a radius of 5 inches.
Utilizing the formulation above:
“`
Space = πr^2
Space = π(5)^2
Space = 25π
Space ≈ 78.54 sq. inches
“`
Subsequently, the world of the circle is roughly 78.54 sq. inches.

Step 2: Convert to Ft
If the circumference shouldn’t be already in ft, convert it to ft. For those who measured the circumference in inches, divide by 12. For those who measured in centimeters, divide by 30.48.
Step 3: Divide by 3.14
Divide the circumference in ft by 3.14 (π). This division offers you the radius of the circle in ft.
Step 4: Multiply by Itself
Multiply the radius by itself to get the sq. radius. This step offers you the world of the circle in sq. ft.
Step 5: Convert to Sq. Inches
For those who want the world in sq. inches, multiply the world in sq. ft by 144. This conversion is critical as a result of there are 144 sq. inches in a single sq. foot.
Instance
Think about you measured the circumference of a circle to be 15.7 inches. To search out the sq. inches:
1. Convert to ft: 15.7 inches / 12 = 1.308 ft
2. Divide by 3.14: 1.308 ft / 3.14 = 0.417 ft
3. Multiply by itself: 0.417 ft * 0.417 ft = 0.174 sq. ft
4. Convert to sq. inches: 0.174 sq. ft * 144 = 25.056 sq. inches
Subsequently, the circle has an space of roughly 25.1 sq. inches.
