Simplify 8r+(-4r)+3 and then solve if r=5

timama [110]

Simplify= 4r+3

Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same

Then the answer if r=5 is 23

Because the equation looks like 4(5)+3

5 times 4 is 20 plus 3 is 23

John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.

raketka [301]

Answer:

The approximate area of the circle is 2462 centimeters².

Step-by-step explanation:

Given:

John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.

Now, to get the area of the circle approximately.

Diameter of the circle = 56 centimeters.

So, the radius (r) of the circle = $\frac{Diameter}{2} =\frac{56}{2}=28\ centimeters.$

Using 3.14 for π.

Now, to get the area of circle by putting formula:

$Area=\pi r^2\\\\Area=3.14\times 28^2\\\\Area=3.14\times 784\\\\Area=2461.76\ centimeters^2.$

Approximately the area of the circle = 2462 centimeters².

Therefore, the approximate area of the circle is 2462 centimeters².
