The circumference of a circle is 20 pi. What is the area of the circle in terms of pi

Area of the circle= square units

Step-by-step explanation:

Circumference of the circle =

Finding the radius of the circle by using the formula of the circumference of the circle;

Circumference of a circle =

=

Dividing by '' both side:

Dividing by '2' both side:

Radius= 10 units

Area of the circle=

Area of the circle= square units

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).

0,0
