A child's toy consists of a cone inside a sphere. The radius
of the sphere, OA, is 6 cm and the radius of the base of the
cone, AC, is 3.6 cm.
(The volume of a sphere of radius R is TR%. The volume
of a cone of base radius r and height h is žarh.)
a Show that VOC, the height of the cone, is 10.8 cm.
b Calculate
i the volume of the sphere
ii the volume of the cone
iii the percentage of the volume of the
sphere not occupied by the cone.
o
6 cm
ac
A
B
3.6 cm

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
