First you should draw yourself a square.Since you know it is a square you can find each side by dividing it by 4. 32/4 = 8. Since it is a square you know that both the length and width are 8. If you draw in the diagonal that is a right triangle. Use the Pythagorean theorem a^2 + b^2= c^2 to find the length of the diagonal.
8^2 + 8^2 = c^2
Total ratio=9+11=20

Answer:what is the least common denominator of the fractions 2/3 and 3/5? HELP PLEASE
Step-by-step explanation:
To calculate the volume of a sphere you must use the formula
v=4/3pir^3
The radius (r) is half of the diameter
r=13.5
v=4/3pi13.5^3
v=10305.99
Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)
