Answer:
c 4.1 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
The sector is only 78 degrees
Take the fraction of a circle and multiply by the circumference to find the length x
x = C* 78/360
= 2 * pi *r * 78/360
= 2 * pi *3 * 78/360
Using 3.14 for pi
= 4.082
Rounding to the nearest tenth
x = 4.1 inches
remember PEMDAS or order of operations
it's the order in which to simplify stuff
P: parenthasees (or grouping symbols like brackets or such), remember to work inside to out
E: exponents (includes square roots since they are fractional exponents)
M & D: multtiplication and divions, I do whichever comes first since division is just multiplication by a fraction
A & S: addition and subtraction, I do whichever comes first since subtraction is addition of a negative
[(30+6)-30] / 9 * 2
parenthases first, do innermost first
(30+6) is innermost parnthaees
no exponents or multipilcation or division so we add to get 36
[36-32] / 9 * 2
simplify parenthasees/brackets
[36-32] is subtraction, so 4
4 / 9 * 2
division
4/9=0.444444444444444444
0.444444444444*2=0.888888888888888 or 8/9
answer is 8/9 or 0.88888888888 which is none of the options for some reason
