Find the perimeter of the figure to the nearest hundredth.<br><br><br> Ps: it is not 30
frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

<u>Step 1:  Add the straight sides together</u>

3+3+3+3+3+3 = 18 ft

<u>Step 2:  Find the perimeter of the semi-circles</u>

The formula for the perimeter of semi-circle:  1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

<u>Step 3:  Add all of them</u>

18 + 18.8 = 36.8 ft

Sylvia took three times in a video game she scored -120 points during her first turn 320 points in her second time and -80 point
sp2606 [1]
Her average score for the 3 turns is 40 because you have to add all of the scores so -80 and -120 is -200 so add that to 320 and you get 120 divide that by 3 because she took 3 turns and you get 40
