AREA OF CIRXLES HELP PLS​

147

I applied the equation for finding the area of a circle

A = 147 cm²

Step-by-step explanation:

A = πr²

A = (3)(7)²

A = 3(49)

A = 147 cm²

Hope this helps!

56/112  or 29/56

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

We have 8 divided into a number as there are 8 participants.

so we can do; 8 x7 = 56 and expand 56 as the median after 4 weeks as 4 weeks is the total

We can divide 56 by 4 and express it must be greater than 8 but no greater than 56-3 = 53 week

Answer mean median and range per week is not conclusive,

Answer mean median per day is not conclusive,

Answer range per day could be shown 112-56=56

As days are 28 x 4 participants = 112 then we have a 50% conclusion to the mean and to the range.
