WebFeb 14, 2024 · The area of a sector with a central angle α = 90° of a circle with radius r = 1 is π/4. To calculate this result, you can use the following formula: A = r² · α/2, substituting: r = 1; and. α = 90° · π/180° = π/2. Thus: A = (1² · π/2)/2 = π/4. Notice that this is also a quarter of the area of the whole circle. WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
