Web24 feb. 2024 · The new circumference is 30 pi cm . Step-by-step explanation: Here, we have that the initial circumference measures 10 pi cm. Mathematically, we have the circumference of a circle as; C = 2 * pi * r. 10 pi = 2 pi r. 2r = 10. r = 10/2 = 5. Now, we want to triple the radius . the new radius becomes 5 * 3 = 15. The new circumference is …

Circumference of a Circle - Definition, Formula,

WebThe arc of the circle is a part of the boundary/circumference of the circle. Two radii meet at the center of the circle to form two sectors. Minor sector; Major sector; ... The radius of sector $= r = 10$ feet. Arc length $= l = 12.56$ feet. Area of the sector without an angle $= \frac{lr}{2} = \frac{12.56\times10}{2} ... Web23 okt. 2014 · The related rate you are given is that of the area A with respect to time t. It is. d A d t = 1 (cm/s) We also know that area is related to radius by. A = π r 2. We differentiate to find that. d A d r = 2 π r. or, alternatively, d A = 2 π r d r. food la bouffe
