What the area of a circle with the radius of 7

About 153.94 units^2

Step-by-step explanation:

The area of a circle can be found using:

We know r, or the radius is 7, so we can substitute that in

Solve the exponent

Multiply

a=153.938040026

Rounded to the nearest hundreth

a=153.94

So, the area is about 153.94 units^2

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
