WebA line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another … WebGiven, Radius of the circle = 28 cm. To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: The circumference of a …
WebIf a 12 0 ∘ sector of a circle has radius 12 cm, what is the perimeter of the sector? The perimeter of the sector is (Type an exact answer, using π ashjeeded.) Previous question Next question WebA circular arc whose radius is 12 cm, makes an angle of 30° at the centre. Find the perimeter of the sector formed. Use π = 3.14. Solution : Given that r = 12 cm, θ = 30° = 30° × (π/180°) = π/6 Perimeter of sector is given by the formula; P = 2 r + r θ P = 2 (12) + 12 ( π/6) P = 24 + 2 π P = 24 + 6.28 = 30.28 Hence, Perimeter of sector is 30.28 cm
WebA circle of radius = 6 or diameter = 12 or circumference = 37.7 feet has an area of: Use the this circle area calculator below to find the area of a circle given its diameter, or other parameters.
