Hello from MrBillDoesMath!
Answer: 30
Discussion:
The area of a circle of radius R is given by the formula
Pi * R^2
We are given that the area is 225 Pi (Not 255 Pi as stated by the author)
Pi * R^2 = 225 * Pi
Divide both sides by Pi :
R^2 = 225 ---> R = 15
The diameter is twice the radius so the diameter = 30.

Step-by-step explanation:
Answer:
- 0.3
Step-by-step explanation:
Slope Intercept Form:
y = mx + b
Slope:
m = slope
Equation:
- 0.3x + 3.7
Slope = - 0.3
Hope This Helps :)
Answer:
x = 7.5
y = 75
Step-by-step explanation:
if one angle of an equilateral triangle is 60 degrees (180/3) then 4x + 2x + 2x = 8x = 60, so x = 7.5
for y, we'll have to take the right triangle. we know that 2x = 15, and MON = 60, so 180 - 60 - 15 = 105.
180 - 105 will give us y, which is 75
There an infinite number of solutions that can be generated by giving different values
