C. Line of symmetry is the correct answer
Answer:
4pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
where r is the radius
The radius of a circle is found by
r =d/2 where d is the diameter
r = 4/2 = 2
So A = pi (2)^2
pi (4)
4pi
Answer:
2.19
Step-by-step explanation:
Answer:
113
Step-by-step explanation:
area of a circle is 3.14*r^2
r=d/2 r=6
3.14*36=113
9514 1404 393
Answer:
- 6 shirts at $8
- 3 shirts at $7
Step-by-step explanation:
Let x and y represent the numbers of $8 and $7 shirts, respectively. Your system of equations can be written ...
x + y = 9
8x +7y = 69
Subtracting 7 times the first equation from the second gives ...
(8x +7y) -7(x +y) = (69) -7(9)
x = 6
Then y is ...
y = 9 -x = 9 -6 = 3
