P(both red)=(10/17)(9/16)
P(both blue)=(7/17)(6/16)
P(both same)= sum of above 2 = (90+42)/(16*17)=132/(16*17)=<span>0.485
coz both same means both blue or both red

We want to find the perimeter of the given figure. We will find that the perimeter of the figure is 35.7 units.
Remember that for a circle of diameter D, the perimeter or circumference is:
p = pi*D
where pi = 3.14
So we have a half-circle and an equilateral triangle, and we know that the equilateral triangle sides measure 10 units each.
Notice that the diameter of the half-circle is equal to the side length of the triangle, then the diameter is D = 10
Then the length of the arc of the half-circle is just given as half the circumference of a circle with a diameter of 10 units, this is:
C = (1/2)*3.14*10 = 15.7
And to this we must add the two sides of the triangle that belong to the perimeter, remember that each one measures 10 units, then the total perimeter is:
Perimeter = 15.7 + 10 + 10 = 35.7

Answer:
what are we trying to do with the problem tho?
Step-by-step explanation:
Ok I got 32.995 I’m not sure what place you need to round to so I kept that throughout my solving process. I’m not too sure if this is right but here is the work that I did in the picture. I didn’t show the distance formula as I used an online calculator lol.
