we know that
Area of the circle is equal to
where
r is the radius
in this problem
therefore
the answer is the option

What is it about. I think I can help you just got to explain what you need to do
Answer:
0.001953125
Step-by-step explanation:
Divide 34 by 512
34 ÷ 512 = 0.06640625
divide 0.06640625 by 34
0.06640625 ÷ 34 = 0.001953125
Check you work
34 × 0.001953125 = 0.06640625
Answer is 3 4 ÷ 5 12 = 3 4 × 0.001953125
<u>Step 1</u>
Convert mixed fractions into fractions
6 2/5 = (6*5)+2) / 5 = 32/5
2 2/3 = (2*3)+2) / 3 = 8/3
<u>Step 2</u>
32/5 ÷ 8 / 3 ; where 32/5 is the 1st fraction and 8/3 is the 2nd fraction
<u>Step 2 (A)</u>
Get the reciprocal of the 2nd fraction:
From 8/3 to 3/8
<u>Step 2 (B)</u>
Multiply 1st fraction to the reciprocal of the 2nd fraction
32/5 * 3/8 = (32*3) / (5*8) = 96/40
<u>Step 2 (C)</u>
Simplify the fraction
96/40 divide by 4 will become 24/10
24/10 divide 2 will become 12/5. The simplest fraction of 96/40
The unit rate is 12/5 = 2 2/5 revolutions per second
