WebFrom there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we leverage pi r squared to figure out that the radius was 6, and then ... WebApr 11, 2024 · Circumference Circle Area = c² / 4π Also, the circle area formula is handy in everyday life – like the serious dilemma of which pizza size to choose. Sector area formula The sector area formula may be found by taking a proportion of a circle. The area of the sector is proportional to its angle, so knowing the circle area formula, we can write that:
WebAug 2, 2024 · If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr 2, to get the diameter. You can transform this into r = √ (A/π) cm. [3] Example WebFrom the diameter and the circumference, we can find the radius and then find the area of a circle. But these formulae provide the shortest method to find the area of a circle. Suppose a circle has a radius 'r' then the area of circle = πr 2 or πd 2 /4 in square units, where π = 22/7 or 3.14, and d is the diameter.
WebFeb 9, 2024 · a stands for the area of the circle. It is the only value expressed in squared units (for example, cm²). You can calculate it as follows: If you know the radius or diameter of the circle, the area of the circle formula is: a = πr² = π × (d / 2)² If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π WebArea = a2 a = length of side Rectangle Area = w × h w = width h = height Parallelogram Area = b × h b = base h = vertical height Trapezoid (US) Trapezium (UK) Area = ½ (a+b) × h h = vertical height Circle Area = π × …
