3-1=2 2X2 = 4 2-1= 1 =3x^2- 4x

Vol = 1/3 pi r^2 h

r = 2n

h = 3n

Therefore

Vol = 1/3.pi.(2n)^2.3n

Vol = 1/3.pi.12n^3

Vol = 4.pi.n^3

The function f(x) is a product of 2 functions of x, so when we differentiate it, we need to use the product rule.

The product rule states that for a function f(x) = g(x)*h(x), f'(x) is given by g(x...

The cake is in the shape of a circle. How many degrees in a circle?

Abi is 9 years old so the angle of her slice is 9 x 10 = 90°, Elvera is 14 years old so her angle is 14 x 10 = 140°. Total angle ...

Integrate this = (3x^3)/3 + (3x^2)/2 + c So y = x^3 + (3x^2)/2 + c Using point (0,0), 0 = 0 + 0 + c so c = 0. Full equation of the curve is therefore x^3 + (3x^2)/2
