Answer:
The answer is C. 904.32 in^3.
Step-by-step explanation:
To find the volume of a sphere with a radius of 6 in, start by using the formula for a sphere, which is V=
. However, for this formula instead of using (), 3.14 will be used.
Now, plug the radius into the formula, and solve for V.
Finally, the answer will be 904.32 in^3.
Answer: 27.2
Step-by-step explanation:
A squared + B squared = C squared 22 is A squared and 16 is B squared and C squared is the hypotenuse and that is what we are figuring out
22squared= 484 and 16 squared=256 484+256=740 and 27.2 squared is 740 I hope this helps
Answer:
x=4
Step-by-step explanation:
sqrt(x+5) = sqrt(x)+1
Square each side
(sqrt(x+5))^2 = (sqrt(x)+1)^2
x+5 = (sqrt(x)+1)^2
Foil
x+5 = (sqrt(x)) ^2 + sqrt(x) + sqrt(x) + 1
x+5 = x + 2 sqrt(x) + 1
Subtract x from each side
5 = 2 sqrt(x) + 1
Subtract 1 from each sdie
4 = 2 sqrt(x)
Square each side
4^2 = (2 sqrt(x))^2
16 = 4 x
Divide by 4
16/4 = 4x/4
4 =x
Check to see if it is extraneous
sqrt(4+5) = sqrt(4)+1
sqrt(9) = sqrt(4) +1
3 = 2+1
3=3
It is a valid solution
