Answer:
3375 
cubic centimeters
Step-by-step explanation:
Trick question: The largest piece is the entire cone.
First lets identify the equation for volume.
V= 1/3 h pi r^2
h=45
r=15
V= 1/3 45 * pi 15^2
v= 15* pi 225
3375 pi
You keep pi because the answer has pi.
Answer:
k = 11
Step-by-step explanation:
What the factor theorem is telling us is that if x + 1 is a factor of 2x - kx²-8x + 5 then when x = - 1 is put into the equation, the result will be 0. That's because x +1 = 0 when x = - 1
f(-1) = 2(-1) - k(-1)^2 - 8(-1) + 5
f(-1) = -2 - k(1) + 8 + 5 = 0
-k*(1) + 11 = 0
-k = -11
k = 11
Answer:
x = 70
Step-by-step explanation:
The total interior angle in a square, even with not a perfect square, adds to 360
Set your formula up as
360 = (x+15) + x + 115 + 90
360 - 115 - 90 - 15 = 2x
140 = 2x
140/2 = x
70 = x
