Michelle found the area of a circle as 78.5 . She used 3.14 for π. What is the radius of the circle? Explain how you found your
NikAS [45]

Answer:

5 units

Step-by-step explanation:

Given:-

- The area of the circle was computed to be A = 78.5

- The value of π is estimated to be = 3.14

Find:-

What is the radius of the circle?

Solution:-

- The area of a circle (A) with radius ( r ) is computed by the following formula:

                            A = π*r^2

- Divide the equation by π :

                            r^2 = ( A / π )

- Take the square root of the entire equation:

                            r = √ ( A / π )

- Substitute the given values:

                           r = √ ( 78.5 / 3.14 )

- Resolve the fraction:

                          r = √25

- The perfect square root of 25

                         r = 5

Answer: The radius of the circle is r = 5 units

Nataliya [291]

Answer:

It is given that a car traveling at 23 mi/h accelerates to 46 mi/h in 5 seconds.

This means that in 5 seconds it's speed continuously increases to reach 46 mi/h from 23 mi/h.

It maintains that speed for 5 seconds and then slows to a stop in 5 seconds.

This means that the speed of the car is constant i.e. 46 mi/h i.e. the graph is a straight horizontal line parallel to the time axis.

And then it decreases to reach 0 mi/h.
