Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm
0.4875 would be your answer because 0.25 times 1.95 in the calculator makes 0.4875
