A stainless steel circle with a circumference of 100 cm is forged. A 22 cm arc of this circle is cut out. What is the
measure of this arc in degrees?
A 69.2°
B 72.9°
C 78 20
0 79.2°

d is the answer

step-by-step explanation:

use a calculator or a graph

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
