Answer:
28cm✨
Step-by-step explanation:
The perimeter of the given square is a + a + a + a
7+7+7+7=28
Have a great time studying.
Answer:
not sure but I feel like 6 because 3x2 is 6
The answer is 58 .
5x5=25
2x2x2x2x2=32
25+32=57
57+1=58
We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
Volume of sphere = 4/3(pi)(r^3)
Given pi = 3.14, r = 10
4/3(3.14)(10^3)
= 4186.66
Now round to hundredths
Solution: 4186.67 cubic meters
