From a circular sheet of radius 4 cm a circle of radius 3 cm is removed find the area of the remaining sheet take Pi is equal to 3.14
tangent to the curve y ଶ + 3x − 7 = 0 at the point (ℎ, ݇) is parallel to line x − y = 4,then value of k is ___?
Smaller area enclosed by the circle 𝑥^2 + 𝑦^2 = 4 and the line 𝑥 + 𝑦 = 2 is (a) 2(𝜋 − 2) (b) 𝜋 − 2 (c) 2𝜋 − 1 (d) 2(𝜋 + 2)
