Answer:
The radius is 6.1 cm
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
There is a typo in the problem.
We know the volume
950 = 4/3 (3.14) r^3
Multiply each side by 3/4
3/4 *950 = 3.14 r^3
712.5 = 3.14 r^3
Divide each side by 3.14
712.5/3.14 = r^3
226.910828 = r^3
Take the cube root of each side
226.910828 ^ (1/3) = r^3 ^ 1/3
6.099371323 = r
The radius is 6.1 cm
9 and 7 are the numerators. The greatest common factor between 3 and 7 is 21. Whatever u multiply the bottom by u have to multiply the top by as well
Answer:
126 cm^3
Step-by-step explanation:
Use volume formula (Bh=V): 21×6=126

Answer:
The shorter side: longer side is 385:512
Step-by-step explanation:
We are given that A man has 166 feet of fencing to build the pen
We are supposed to find If one end is a square, find the outside dimensions, if a = 6.
Side of square = x
Perimeter of square =
a=6
Length of rectangular part = x+a = x+6
Breadth of rectangular part = x
Perimeter of rectangular part = 2(l+b)=2(x+6+x)=2(2x+6)
So, ATQ
4x+2(2x+6)=166
4x+4x+12=166
8x=154
x=19.25
Shorter side = 19.25
Longer side = x+6=19.25+6=25.6
So, the shorter side: longer side =
Hence the shorter side: longer side is 385:512
