Answer:
the answer I got was 2878.3
B)
here,
A to B = 62
C To B = 11
A to C = ?
now,
so, 62 - 11 = 51
therefore a to C Is 51 cm
plz mark me brainliest ok
plz follow me
A)
Here,
A to B = 13
A to C = 26
total = ?
now,
A to B + A to C
13 + 26 = 39
Therefore,
total number is 39
If you mean the question 3p=0.064 then to find the answer you divide 0.064 by 3 to get 0.213333.....
<span>OK, here's a *very* approximate "creative" method:
</span><span>
sin(a+b)=sin(a)cos(b) + cos(a)sin(b) </span>
<span>
choose a=30deg and b=5deg </span>
- sin(a)=0.5 (exact)
- b is a small number so we say sin(b)~b (in radians). We can do a long division for this: 3.14/36 = 0.087 radians
- similarly, for b sufficiently small, cos(b)~1
<span>- now we only need cos(a) = sqrt(3)/2. We can approximately calculate sqrt(3) as 1.73, (by trial-and-error or better, by using the Babylonian method; so sqrt(3)/2 = 0.865 </span>
<span>
Finally, sin(30 + 5) = (0.5 x 1) + (0.087 x 0.865) = 0.575 (calculating more digits is of no use because the sin(b)=b and cos(b)=1 are quite inaccurate approximations). </span>
<span>So that wasn't all too much effort, and we're close to the correct answer (0.574)
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
The radius is C: 15.9 meters
Step-by-step explanation:
Multiply 3.14 by 2, =6.28
Divide the circumference (100) by 6.28
That would equal 15.9235, and when simplified you will get 15.9!
hope that helps
