Find the area of this circle. Use 3.14 for a
68 mm
The area of the circle is about mm?
(Round to the nearest hundredth as needed.)

(3.14)(68)^2=14519.40mm^2      if 68mm is the radius

Step-by-step explanation:

what

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
