Webb16 mars 2024 · The radius of a circle was increased by 1%. Formula Used: area of circle = 22/7 × r 2; r = radius of circle. percentage increment/increased = (final area - initial area)/initial area × 100. Calculation: ⇒ initial area of circle = 22/7 × r 2 . final radius = r × 101/100 = 1.01r. ⇒ final area of circle = 22/7 × (1.01r) 2. ⇒ ... WebbIt takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the center of a circle. This makes sense, because the full circumference of a circle is 2\pi r 2πr, or 2\pi 2π radius lengths. Why use radians instead of degrees?
