The equation for the area of a circle is A = pi times r^2
The radius is half the diameter, making it 5.
A = pi times 5^2
Simplify to: A = pi times 25
A = 78.5
Step-by-step explanation:
12x-8=64
we transposed
12x=64+8
12x=72
we divide both by 12
12x/12=72/12
x= 6
Answer:
I belive the exact answer would be 115.0125. So rounded would probally be 115
Let’s make an equation 5x=15.25. We should get x by itself by dividing both sides by 5. Which should leave x=3.5, which would mean he’d have to run faster, so no. It’s not reasonable
(A)
Vertex:(0,4)
Focus : (0, -7/2)
Axis of symmetry: x = 0
Directrix : y = - 9/2
(B)
Vertex:(-3,-4)
Focus : (-3,-31/8)
Axis of symmetry: x = -3
Directrix: y = - 33/8
