What is the length of the arc on a circle with radius 16 ft intercepted by a 60° angle? use 3.14 for π . round the answer to the hundredths place. enter your answer in the box.

Hello!

To find the length of the arc on a circle with a radius length of 16 feet, and is also intercepted by a 60 degree angle, we need to change it from degrees to radians, and then multiply it by 16 feet, which is the radius.

To change from degrees to radians, we will to multiply it by π/180.

60 × π/180 = π/3 rad

Now, we multiply π/3 rad by 16 feet.

π/3 × 16 = 16π/3

This answer would be exact, but we are needed to substitute π for 3.14.

16(3.14)/3 = 16.75

Therefore, the length of the arc is equal to about 16.75.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
