volume - pi*r^2*H
Lets use 3.14 for pi
R = radius which is half the diameter so half of 3 is 1.5
H = 6
so volume = 3.14*1.5^2*6 = 42.39in^3
Answer:
The answer to your question is y = 2(x + 8)²
Step-by-step explanation:
This is a vertical parabola that opens upwards
The distance from the vertex to the directrix is 1/8 so p = 1/8.
Equation
(x - h)² = 4p(y - k)
h = -7
k = 0
p = 1/8
Substitution
(x + 8)² = 4(1/8)(y - 0)
Vertex form equation
(x + 8)² = 1/2(y)
y = 2(x + 8)²
x² + 16x + 64 = 1/2y
2x² + 32x + 128 = y
General equation
2x² + 32x - y + 128 = 0
Answer: 18080!
Step-by-step explanation:400 x 450
1. Multiplying from the oneths place ( turning 45.2 into 450)
2x0=0 2x0=0 2x4=8 = So the first answer is 800
2. Multiply from the tenths place
5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000
Multiplying the hundredths place
4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600
800 + 2000 + 1600 = 18080 Hope this helped! :)
Answer:
it would be 5n
Step-by-step explanation:
10+8=18 and 13+5=18
It is B 80. Because it is 40 x 2 = 80. Hope thishelped
