If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)
solniwko [45]

Answer: 113.04

Step-by-step explanation: The equation for the area of a circle is pi r squared so you have to find the radius first. To find the radius, find the diameter first. A way to do this which was easiest for me was dividing 37.68 by pi (3.14), which is 12. Divide the diameter by 2 to find the radius, 6.

Now use the equation from the beginning, pi r squared. So plug in pi as 3.14, then the radius as 6. It is important to always square the radius first, which would be 36. Now multiply 36 by 3.14, and there should be your answer.

2/3 x = 30

x = 30/2/3

x = 30×3/2

x = 90/2 = 45

The number is 45

2/3 ×45= 90/3 = 30

I'm stuck on b.<br>please help me!!!!​
Sloan [31]

The area under the speed curve tells you how much distance the vehicle covers.

The distance for first 30 s corresponds to the area of a rectangle with height <em>k</em> m/s and length 30 s, or

(<em>k</em> m/s) (30 s) = 30<em>k</em> m

The distance for the last 20 s corresponds to the area of triangle with height <em>k</em> m/s and length 20 s, or

1/2 (<em>k</em> m/s) (20 s) = 10<em>k</em> m

If the total distance traveled was 1.7 km = 1700 m, then

30<em>k</em> + 10<em>k</em> = 1700

40<em>k</em> = 1700

<em>k</em> = 42.5
