Answer:
the original volume is lesser than the new volume by 242.47 in³
Step-by-step explanation:
Volume of a cone is;
V = ⅓πr²h
Where;
r is radius
h is height
For the original chamber;
r = 5.7/2 = 2.85 inches
h = 12 inches
Volume of this original chamber is;
V_orig = ⅓ × π × 2.85² × 12
V_orig = 102.02 in³
In the new design, the chamber is scaled by a factor of 1.5.
Thus;
r_new = 2.85 × 1.5 = 4.275 inches
h_new = 12 × 1.5 = 18 inches
V_new = ⅓ × π × 4.275² × 18
V_new = 344.49 inch³
V_new - V_orig = 344.49 - 102.02 =
Thus, the original volume is lesser than the new volume by 242.47 in³
Answer:
The answer is B
Step-by-step explanation:
q=1/4,
32×1/4=8
8×1/4=2
2×1/4=1/2 etc
Answer:
A = 90, B =18
Step-by-step explanation:
From the question
The weight of meteorite A is five times the weight of meteorite B, ill get this equation
A = 5B
if their sums of their weights is 108 tons, find the weight of each, ill get this equation
A+B = 108
Now since I have two equation, u just have to solve it simultaneously
A = 5B ( equation 1)
A+ B = 108 (equation 2)
From equation 2
A+B = 108
B = 108 - A ( equation 3)
Now ill put equation 3 into equation one
A = 5B
A = 5 (108 - A)
A = 540 - 5A
6A = 540
A = 90
Now since u know A = 90, just choose any of the equations the question gave u, either equation 1 or 2, they will give u the same answers, I'll prove it to u
Equation 1
A =5B
90 = 5B
B = 90/5
= 18
Equation 2
A+B = 108
90 + B = 108
B = 108 - 90
= 18
So at the end, A = 90 ton, B = 18 ton
I have to think this again. be back later x=2.2267(55).
