We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.
We will use arc length formula to solve our given problem.
, where,
r = Radius of circle,
= Central angle corresponding to arc.
We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.
Upon rounding to nearest hundredth, we will get:
Therefore, the radius of circle H is approximately 63.88 miles.
Answer:
is scientific notation of 0.0765
Step-by-step explanation:
For scientific notation , follow the following notation:
-------->(equation 1)
Let, 
In standard form
As decimal point move 2 places from left to right, therefore
b = -2
Put the value of 'a' and 'b' in (equation 1)
is scientific notation of 0.0765
I believe the answer is the first one
It would be B, because BC does not necessarily have to be equal to CE, as they are not congruent
