Find the area and the circumference of the circle with the radius 6yd.
who's the value 3.14 for pie and do not round your answers.
be sure to include the correct units in your answers.

Step-by-step explanation:

The formula of an area of a circle:

The formula of a circumference of a circle:

r - radius

We have r = 6yd.

Substitute:

If you want round the answers, then use π ≈ 3.14

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
