Answer: 1,000,000,000,000,000,000,000,
Step-by-step explanation:
Answer:
151 in^3
Step-by-step explanation:
The rocket consists of two shapes - a cone and a cylinder
the volume of the plastic = volume of cone + volume of cylinder
volume of a cylinder = nr^2h
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
the diameter is the straight line that passes through the center of a circle and touches the two edges of the circle.
A radius is half of the diameter
Radius = 5/2 = 2.5
Height of cone = 11 - 6 = 5
Volume of plastic = (22/7) x (2/5^2) x 6 + (1/3) x (22/7) x (2/5^2) x 5 = 117.9 + 32.7 = 150.6 in^3 = 151
Answer:
C
Step-by-step explanation:
because to solve it you are seeing which number divises 52 to get you 13
so using the inverse you just need to use multiplication
Answer:
1) Centre: (-4,-8)
Radius: sqrt(93)
2) y = ¼x² - x + 4
Step-by-step explanation:
1) 4x² + 8x +4y² +16y -13 = 0
h = -8/2 = -4
k = -16/2 = -8
(-4)² + (-8)² - (-13) = r²
r² = 93
r = sqrt(93)
sqrt: square root
2) h = (0+4)/2 = 2
y = a(x - 2)² + k
4 = a(0-2)² + k
4 = 4a + k
k = 4 - 4a
12 = a(8-2)² + k
12 = 36a + k
12 = 36a + 4 - 4a
8 = 32a
a = ¼
k = 4 - 4(¼) = 4 - 1 = 3
y = ¼(x - 2)² + 3
y = ¼(x² - 4x + 4) + 3
y = ¼x² - x + 1 + 3
y = ¼x² - x + 4
