C4 Mathematics Edexcel June 2011 Question 3

A hollow hemispherical bowl is shown in Figure 1. Water is flowing into the bowl. When the depth of the water is h m, the volume V m3 is given by

V = 1/12 π h2(3 - 4h), 0 ≤ h ≤ 0.25

(a) Find, in terms of π, dV/dh when h = 0.1

C4 Mathematics Edexcel June 2011 Question 4

Figure 2 shows a sketch of the curve with equation y = x3ln(x2 + 2)

The finite region R, shown shaded in Figure 2, is bounded by the curve, the x-axis and the line x = √2

The table below shows corresponding values of x and y for y = x3ln(x2 + 2)

(a) Complete the table above giving the missing values of y to 4 decimal places.

(b) Use the trapezium rule, with all the values of y in the completed table, to obtain an estimate for the area of R, giving your answer to 2 decimal places.

(c) Use the substitution u = x2 + 2 to show that the area of R is

(d) Hence, or otherwise, find the exact area of R.
