Circumference of the circle as 15 pi inches find the diameter
Answers
The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r
Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.
π*diameter=15*π
We can divide π from both sides.
diameter=15

Answer:
124 degrees since all angles should equal 180 degrees.
Answer:
So if you think about it, 180° is a full angle. So if you take the 180° and subtract the 19° and the 37° you should get your remaining angle. the answer I got for the angle is 124°. To check your work, 124° + 19° + 37° = 180°

a. w^2+3w-3
b. w^2
c. w^2-9
d. w^2+w
Answers
Answer:
First one is d and second one is c
Step-by-step explanation:
(6x+7)(x-8)
(6x)(x) = 6x^2
(6x)(-8) = -48
(7)(x) = 7x
(7)(-8) = -56
Add all like terms together and you get choice d.
(w+3)(w-3)
(w)(w) = w^2
(w)(-3) = -3w
(3)(w) = 3w
(3)(-3) = -9
Add all like terms together and you get choice c
