Find the exact circumference of a circle with diameter equal to 8 ft. 8 ft. 16 ft. 64 ft.

Step-by-step explanation:

we know that

The circumference of a circle is equal to

where

D is the diameter

we have

substitute

Step-by-step explanation:

We know that formula to calculate the circumference of a circle is given by :-

, where d is the diameter of the circle.

Given: The diameter of the circle :

Then , the circumference of a circle is given by :-

Hence, the exact circumference of a circle with diameter equal to 8 ft =

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
