WebThis tool will calculate the radius of a circle from the circumference, and will convert different measurement units for circumference and radius. Formula. The formula used to calculate the circle radius is: r = C / (2 · π) … WebAug 21, 2024 · Given: Area of circle 1 = 154 cm 2. Radius of circle 2 = 21 cm. Calculation . Area of circle 1 = π × radius 2. ⇒ 154 = 22/7 × radius 2. ⇒ radius 2 = 49. ⇒ Radius = √49. ⇒ Radius = 7cm. So the circumference of cicle 1 = 2π × radius. ∴ Circumference of circle 1 = 2 × (22/7) × 7 = 44 cm. Radius of circle 2 = 21 cm. ∴ Circumference of circle 2 = 2 × …
If the area of a circle is 154 cm^2 , what is the perimeter of
WebThe distance between the center of the circle to its circumference is the radius. The diameter is always double the radius. Hence, the formula is derived by dividing the diameter by 2. ... Question 3: If the area of a circle is 154 cm … WebThe following equations show how the radius and diameter relate to the circumference. The equation for circumference of a circle is: c=\pi d c = πd. If written instead in terms of the radius, the circumference calculation is instead: c = 2 \pi r c = 2πr.
