WebDec 14, 2024 · Determine the radius of a circle. Let's assume it's equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm. You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Finally, … Circle terminology consists of the definitions of: Circumference – the distance around … WebAboutTranscript. The area of a circle is pi times the radius squared (A = π r²).

WebCircumference of a cicle in terms of radius:. Circumference = 2·π·r = 2·3.14·1.75 = 10.99 (*) In terms of diameter:. Circumference = π·d = 3.14·3.5 = 10.99 (*) In terms of area:. Circumference C = √ 4·π·A = √ 4·π·9.62 = 10.99 (*) (*) 11 meters exactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operations above … WebWhen the radius of a circle is known, the circumference can be calculated by using a formula. The formula is C = 2 π r, where C is the circumference and r is the radius. The value of π = 3.14159 (to 5dp). If a diameter is given use C = π d. This is the same formula, as 2 r = d. A circumference is a linear measurement; that is, it is a line. north east fife council election results
