Answer:
B
Step-by-step explanation:
The expression can be written as
The - can be taken out from under the radicand and a 2 can be factored out of the expression to leave you with the expression
Answer:
A. (125.6 in)
Step-by-step explanation:
R = d / 2 = 40 / 2 = 20 in
Circumference is:
S = 2*π*R=2*3.14*20=125.6 in
The length of both AB and DC is the same.
19 degrees
We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.
360 - 19 = 341
DBC = 341 degrees
Hope this helps!! :)
Step-by-step explanation: The reciprocal of 20/32 is 32/20. Reciprocal is just flipping a number. For an example: The reciprocal of 98/12 is 12/98.
Hope this helps! :D
