Oksi-84 [34.3K]

Answer:Hi,

Twice the number is 2x

Five less than twice the number is 2x-5, which is given as 9

or, 2x = 14

or x=7

Thus the number is 7.

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
const2013 [10]

Answer:

28.26 units

Step-by-step explanation:

We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.

A = π(3^2) or A = π * 3 * 3

When you substitute pi for 3.14, you'll end up getting 28.26 units.

Hope this helped! :)
