Answer:
Number is 19
Step-by-step explanation:
denote the number by x.
the line says:
5x - 20 = 18 + 3 x
Subtracting 3x form both sides
2x - 20 = 18
adding 20 to both sides
2x = 38
dividing both sides by 2
x = 19

A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
