1. a circle has radius of 3cm. how does the circumference of the circle compare to the area?

2.a circular piece of metal has a radius of 3.5 meters. the metal sells for $3.25 per m².

what is the total cost of the circular piece of metal?

use 3.14 for pi

3.a 12-inch diameter pizza has 22 calories per square inch.

about how many calories are in the entire pizza?

use 3.14 for pi

1/4 because there is 4 grades.

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).
