Answer:
We use ratio and proportion
If EC$ 2.50 = US$ 1.00
Then EC$ 20.00 = US$ 20 × 1 / 2.50
= US$ 8.00

Answer:
A square root of a number is a value that, when multiplied by itself, gives the number.
Examples:
4 multiplied by itself is 16. Therefore, the square root of 16 is 4.
(4 x 4 = 16)
The same goes for every number.
(3 x 3 = 9) square root of 9 is 3
(5 x 5 = 25) square root of 25 is 5
By definition, the volume of a cone is given by:
v = (pi * r ^ 2 * h) / 3
Where,
r: radius
h: height
Clearing the radio we have:
r = root ((3 * v) / (pi * h))
Substituting values:
r = root ((3 * (256)) / (3.14 * (16)))
r = 3.91 cm
Answer:
The radius of the cone is:
r = 3.91 cm
