A right circular cone, A, has height 100 cm and base radius 30 cm. The shaded solid, F, is formed by removing the right circular cone, B, of height 20 cm from the top of A, as shown in Figure 3
The volume of F is k π cm3 where k is an integer. (a) Find the value of k.

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
