Answer:
Volume of sphere A = 128x (Approx.)
Step-by-step explanation:
Given:
Radius of sphere A = 2 x Radius of sphere B
Volume of sphere B = 16x
Find:
Volume of sphere A
Computation:
Volume of sphere = (4/3)(π)(r)³
Volume of sphere B = (4/3)(π)(r)³
16x = (4/3)(π)(r)³
16x = (4/3)(22/7)(r)³
16x = (88/21)(r)³
Radius of sphere B = 1.56∛x Approx.
Radius of sphere A = 2 x Radius of sphere B
Radius of sphere A = 2 x 1.56∛x
Radius of sphere A = 3.12∛x Approx.
Volume of sphere A = (4/3)(π)(r)³
Volume of sphere A = (4/3)(22/7)(3.12∛x)³
Volume of sphere A = (88/21)(30.37∛x)
Volume of sphere A = 127.27x
Volume of sphere A = 128x (Approx.)
Answer is B
Step-by-step explanation:
You have the side opposite the angle and the Hypotenuse so use soh
Sine(x) = opposite/Hypotenuse
Sine(x) = 9/19
X = sin-1(9/19) - - - - - here the - 1 is to the power of
X= 28,27371363
X= 23,3
My Work/Reasoning:
First we find the sum of 1/3 and 1/5.
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal.
turns into
Finally, we simplify.
Answer:
Step-by-step explanation:Area = 1/2(b1 + b2)x h
Area = 18,000 ft^2
b1 = 80 ft
b2 = 100 ft
18,000 = 1/2(80 + 100) x h
36,000 = (180)h
h = 36,000/180
h = 200ft.
This is the distance between streets.
Hope this helps :-)Area = 1/2(b1 + b2)x h
Area = 18,000 ft^2
b1 = 80 ft
b2 = 100 ft
18,000 = 1/2(80 + 100) x h
36,000 = (180)h
h = 36,000/180
h = 200ft.
This is the distance between streets.
Hope this helps :-)
I divided 8745 by 8 and got 1005 so i would say 1000
