What is the area of a circle with a radius of 1/2 inch

The area is approx. 0.79 inch^2.

Step-by-step explanation:

To solve, use the area of a circle formula: pi*r^2.

Then plug in 1/2: pi*1/2^2=0.7853

Round to the nearest hundredth: 0.79.

Hope this helps! :P

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

can you rephrase the question ? it is unclear : -)
