M=4
first we take the 4.5 to the other side and we also take the 12 to other side so we get
1.5m=6
we divided each side we get m=4
A= 360
B= 2(12)²(7)/120= 2016/120=16.8
Answer: X = 13
Step-by-step explanation:

So, the radius is 
The circumference is given by 
Insert the values

Thus, the circumference of the circle is
Answer:
27 in²
Step-by-step explanation:
The area (A) is calculated as
A = πr² ( r is the radius ) , then
A = π × 3² = 3 × 9 = 27 in²
