Find the volume using the shaded base. T F The same volume can be found using the 3-4-5 triangle as the base and a 12 cm height. T F The height of the pyramid using the 5-12-13 base is 2.4 cm. The surface areas of two similar cylinders are 8 pi in^2. Find the following ratios: Area I/Area II = a^2/b^2 = r_1/r_2 = h_1/h_2 = a/b = Volume I/Volume II = a^3/b^3 =

Solution

20.

Ratios Area of the figures can be found out if you know the ratio of sides.

i) Area ratio = 8/18
ii) Side ratio = sqrt(8/18) = 4/9
iii) Volume ratio = 4/9*(2/3) = 8.27
