Answer:
254.47
Step-by-step explanation:
the area of a circle can be found using the formula
pi(radius)^2
in your problem, the radius is 9. Plug it into the equation
pi(9)^2
9^2 is 81
81(pi)
pi is about 3.14
area is 254.47

Answer:
solving for x
Step-by-step explanation:
4 or -6
Divide the diameter by 2 to get the radius and then plug into cone volume pi*r^2*h/3 which is a bit under 160 so the answer is A
Answer:
y= 4x - 21
Step-by-step explanation:
1. 3-7 over 6-7 and you get -4 over -1 so your slope is 4
2. put it in point-slope and solve
3. you should get y = 4x - 21
F i s h, 2 + 2 = fish yes indeed
