Step-by-step explanation:
thats it
A full circle has 360 degrees, which means that 100% of the circle is 360 degrees. First convert the percentage into a decimal. If you multiply 360 by 0.90, you get the degree measure that corresponds to the percentage, which is 324.
Answer: The area in terms of pi is 9(pi)
The approximate value for the area is 28.3
A = pi*r^2
r = 3
3 * 3 = 9
A = pi(9)
When pi = 3.14
3.14 * 9 = 28.26 but it rounds up to 28.3
15
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 15.
