A beach ball is a sphere, so we will need to know how to find the volume of a sphere. V=4π(r³/3) We have the diameter, but not the radius. To find the radius, it is half of the diameter. 10÷2=5 Now let's plug it in. 4π(5³/3) Let's solve. 4π= 12.56 5³= 125 125÷3= 41.67 (repeating 6) 41.67×12.56= 523.3752 523.33 cubic inches is the volume of air contained inside the beach ball. The reason I picked that answer is because we rounded up to 41.67, when there was a repeating 6. So we should expect for the answer to be a couple decimals lower from the answer we got. Tell me if this helps!!
area of a square or rectangle you just multiply length time width. which would be 196ft. You do not specify what shape you need the area of. There are different formulas for all of them.
In order to do this problem, we need to plug in for x. When we plug it in we get . After this we can start by multiplying. When we multiply we get . Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of .
