What is the circumference of a sphere with a diameter of 64ft

4096π ≈ 12867.96 ft

Step-by-step explanation:

The circumference of a sphere is denoted by: C = 4πr², where r is the radius.

We know that the diameter is twice the radius, so since the diameter is 64, then the radius is 64/2 = 32 feet.

Now, plug 32 into the equation:

C = 4πr²

C = 4π * 32² = 4096π ≈ 12867.96 ft

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
