What is the radius of the cone?
an oblique cone has a height equal to the diameter of the
base. the volume of the cone is equal to 18x cubic units.
2 units
3 units
6 units
9 units

Radius = 3 units

Step-by-step explanation:

The volume of the cone is equal to [tex]18\pi[\tex] cubic units.

Also given that diameter is equal to height. Hence h = 2r

Volume of cone is given as

[tex]V=\frac{1}{3}\pi r^2h[\tex]

[tex]V=\frac{1}{3}\pi r^2(2h)[\tex]

Given

[tex]V = 18\pi[\tex]

[tex]18\pi=\frac{2}{3}\pi r^3[\tex]

[tex]18=\frac{2}{3}r^3[\tex]

[tex]r^3=\frac{3}{2} \times 18[\tex]

[tex]r^3=27[\tex]

[tex]r=3[\tex]

And hence radius is 3 units.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
