WebEssentially, you need to square some linear measure of the circle to get to an area. The radius and the circumference are in any case related by a constant - $2\pi$ - and it happens that squaring the radius gives the simplest constant to obtain the area. There is a pretty visual of how the area and radius are related here. WebApr 24, 2024 · $250 = 2\times \pi \times r$ ... Diameter of the tree $= 2\times r = 2 \times 7.62 = 15.24$ ft. 3. ... Perimeter of the square $= 4\times a = 4 \times 10 = 40 cm$. If the same wire is used to form a circle, the overall length of the boundary or the surface remains the same. Hence, the circumference of the circle $= 40$ cm.

WebAug 10, 2012 · See answer (1) Copy. Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter.
WebMar 8, 2024 · Pi can be used to find an area by multiplying the radius of the circle squared times pi.
