What is the area of a circle with a radius of 8 inches? use = 3.14

For this case we have by definition, that the area of a circle is given by:

Where:

A: It is the radius of the circle

They tell us as data that the radius is 8 inches.

Substituting we have:

Thus, the area of the circle is

its not b

step-by-step explanation:

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
