The radius of a cylinder is 3x - 2 cm. the height of the cylinder is x + 3 cm. what is the surface area of the cylinder? use the formula a = 2πr^2 + 2πrh. a. 2π(3x^2 + 10x - 8) b. 2π(12x^2 + 7x - 2) c. 2π(12x^2 - 2x +13) d. 2π(12x^2 - 5x -2)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
