Question

A cyclinder has a volume of 703 cm3 and a height of 18.5 cm. What can be concluded about the cyclinder? Check all that apply.

The formula for the volume of a cyclinder can be applied to find the area of the base.
To find the area of the base, multiply volume and height.
The radius of the cyclinder is half the height.
The area of the base is 38 cm2.
To verify the solution is correct, substitute the given measures and the solution into the equation and verify the result is a true statement.

Answer 1

1 , 4 , & 5 ... which is also a , d, & e

Explanation:

Answer 2

Option (i), (iv) and (v) are correct

Explanation:

Cylinder volume = 703
`cm^(3)`, height = 18.5 cm

(i) Volume or area of the cylinder =
`\pi r^(2) h`

The formula for the volume of a cyclinder can be applied to find the area of the base.

Option (i) is correct

(ii) Volume or area of the cylinder =
`\pi r^(2) h`

The volume should be divivded by height to get the area

Option (ii) is wrong

(iv) Area of the base =
`(703\pi )/(18)` = 38
`\pi cm^(2)`

Option (iv) is correct

(iii) The radius of the cyclinder is half the height.

`(38)/(2)` = 19 cm not 18.5 cm

Option (iii) is wrong

(v)Area of the base =
`(703\pi )/(18)` = 38
`\pi cm^(2)`

Option (v) is correct
