Answer:
7x^2 (the first choice)
Step-by-step explanation:
7x^2
4x+3x = 7x
(4+3)x = 7x
7x
All are 7x except for the first one which is 7x^2
Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
Answer:
• you have correctly identified the radius as 157 miles
• 77,398 square miles is the coverage area
Step-by-step explanation:
The area of a circle is given by the formula ...
A = π·r^2
Filling in your numbers and doing the arithmetic, we get ...
A = 3.14·(157 mi)^2 = 77,397.86 mi^2
The area is approximately 77,398 square miles.
