your question answer is 12360
Answer:
28 percent
Step-by-step explanation:
Exact Area = 98pi
Approximate Area = 307.8760800518 (use calculator stored version of pi)
Approximate Area = 307.72 (using pi = 3.14)
Units are in square millimeters
======================================================
Explanation:
In 60 seconds, the hand sweeps out a full circle of radius 14. The area of this circle is
A = pi*r^2 = pi*14^2 = 196pi
Half of this is what the hand sweeps out in 30 seconds, so A/2 = (196pi)/2 = 98pi is the exact area it sweeps out. Your calculator would then show 98pi = 307.8760800518 approximately
If instead you use pi = 3.14, then the approximate area is 98*3.14 = 307.72

What’s the question?
Answer:
It is 26cm.
Step-by-step explanation:
Do Pythagorean theorem, a^2+b^2=c^2
So 24^2+10^2,
576+100,
676.
Next, we square root it to simplify c^2 to get c by itself
(sqrt)676,
26.
