Answer:
About 339.12 (using 3.14)
About 339.29 (Using PI function on a calculator)
It should say on top if you should use 3.14 or the pi function
Step-by-step explanation:
So find the areas of the circle first, the radius is 3 so we square that and times pi becuase circle of area is pi*raidus^2
So you’ll get 9 Pi
Now there are 2 so we double that
Thats 18 Pi
Now the middle, I‘d like to think of t like a soda can, if you slice a line in the middle And flatten out the curve, you’ll get a. Rectangle which is L*W. Now we know one side (15) and now the other side is just the circumfrcne of the circle (Circumfrnce is the pereimtr of the circle). Now Circumfrnce formula is either 2*radius*pi or just pi*diameter. So we only have radius so 3*2 is 6, 6*pi is 6 pi. Now we multiply 6 pi and 15 which is 90 Pi. Now 90 pi + 18 Pi is 108 pi. Now it depend on what the directions asked, if asked to use 3.14 for pi, its about 339.12 but if asked to use pi function, it’s be 339.29. If asked to use other less common ones, use multiply the thing they asked you to use by 108.
25%. You have:
100% : 260
?% : 65
-> % = (100 x 65)/260 = 25%
Answer:
45
Step-by-step explanation:
The different pairs of individual can be computed using rule of combination.
The combination is denotes as nCr.
nCr=n!/(r!(n-r)!)
In the given problem n=total candidates=10 and r= Selected candidates=2.
10C2=10!/(2!(10-2)!)
10C2=10*9*8!/(2!8!)
10C2=90/2
10C2=45
So, 45 different pairs of individuals can be selected.

See below for answer.
Step-by-step explanation:
RP/RT =RQ/RS Given
∠R = ∠R
ΔPQR similar to Δ TSR If the measures of two sides of a triangle are proportional to the measures of two corresponding sides of another triangle and their included angles are congruent, then the triangles are similar.
