Answer:
Diameter of a sphere formula is d=2 * r
Step-by-step explanation:
Answer:
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2) (see below for explanation)
If volume = 34, d ≈ 4
Step-by-step explanation:
The volume of a sphere is:
V = (4/3) · π · r³
To find the diameter, you need to find the radius first. Isolate it to one side:
[tex]\frac{V}{(4/3)(pi)}[/tex] = r³
r³ = [tex]\frac{V}{(4/3)(pi)}[/tex]
∛r³ = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
So you would first multiply 4/3 by pi, then divide volume by that. Then cube root the whole thing. This will get you the radius.
Double this. This will get you the diameter.
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2)
If the volume is 34, then:
d = {∛ [tex]\frac{34}{(4/3)(pi)}[/tex]} x (2)
4/3 (pi) = 4.188...
34/41.88... = 8.116...
∛8.116... = 2.009...
2.009...(2) = 4.019...
d = 4.019389542
d ≈ 4

Which solid figure could be formed from the net shown?
O rectangular prism
O triangular pyramid
cube
O square pyramid
Answer:
square pyramid
Step-by-step explanation:
It's definitely not rectangular prism because they have faces all with 4 sides, 4 of these faces only have 3 sides. I'm not sure what you mean by triangular pyramid cube. I call this shape a square - based pyramid which has a square base and 4 triangles that join to a point making a pyramid and square pyramid seems like it's just a different name for the same thing.
Can someone plz help me with this one problem plzzzzz!!!!
From 4 p.m. to 1 a.m. the temperature fell by 2 °F each hour. At 11 p.m. the temperature was 0 °F. Using 11 p.m. as a reference point, Carla calculated the temperature using the expression (-2) × (2). What temperature did she find?
A.
the temperature 2 hours before 11 p.m.
B.
the temperature 3 hours before 11 p.m.
C.
the temperature 2 hours after 11 p.m.
D.
kthe temperature 3 hours after 11 p.m.
The answer to this question (I think) would be B.
The -3 Is referring to the drop in temperature and the -2 Is referring to the number of hours before 8 p.m.

Tom has a part-time job. On Wednesday, Tom earned $20.50, and on
Thursday he earned $36.21. On Friday, Tom earned twice as much as he
did on Wednesday. How much did Tom earn altogether for the three days?
Answer:
97.71
Step-by-step explanation:
$20.50 (Wednesday) + $36.21 (Thursday) = $56.71 Since Tom is getting twice as much he did on Wednesday ($20.50), we'll be doing this: $20.50 x 2 (which equals 41 or $41.00) and add it to $56.71
$56.71 + $41.00 = $97.71 So, this means that Tom earned $97.71 altogether for three days
can someone please do this on a separate piece of paper if your helping me with the whole page if not can you just type the answer for number 2 it would be very helpful! i will give a brainlist
Answer:
50 dog walks in 10 hours (1 month)
Step-by-step explanation:
If Darius made 10 dog walks in 2 hours, then in one month, it took Darius 10 hours to make 50 dog walks.
Using the first formula, 2 hours ÷ 1/5 = 10, then
10 hours (in one month) ÷ 1/5 = 50 dog walks.
Hope this helps!
In problem #1, rewrite the problem using the reciprocal (the inverse) of 1/5 to 5/1 and change the division sign to multiplication. Do this for both equations.
Problem 1.) Write 2 ÷ 1/5 = 2 x 5/1 = 10.
Problem 2.) 10 ÷ 1/5 = 10 x 5/1 =50.
Problem 3.) Just explain that in one month, it took Darius 10 hours to walk 50 dog walks using the formula from problem 2 above. Good Luck!

Find the area of the figure to the nearest thousandth.
Answer:
236.625 [tex]ft^{2}[/tex]
Step-by-step explanation:
In this question you need to figure out the area of the circle and the rectangle separating them. You would use this equation:
[tex]A=\pi 7.5^{2} +(4*15)[/tex]
Multiply everything in the parentheses to get the equation:
[tex]A=\pi 7.5^{2} +60[/tex]
Then square 7.5:
[tex]A= \pi 56.25+60[/tex]
Then multiply 56.25 by pi:
[tex]A=176.625+60[/tex]
Add the last two terms together to get the area of the figure which is :
[tex]A=236.625[/tex]
