Acontractor is building a circular swimming pool. the radius of the circle 14 feet. he needs to know the circumference in order to buy tile to put around the edge of the pool. what is the circumference if he uses =22/7 ?
44ft
616ft
88ft

Option 3rd is correct

the circumference of the  a circular swimming pool is, 88 ft

Step-by-step explanation:

Circumference of the circle(C) is given by:

where,

r is the radius of the circle.

As per the statement:

A contractor is building a circular swimming pool. The radius of the circle 14 feet.

⇒ r = 14 ft

Substitute the given values in [1] we have;

Simplify:

Therefore, the circumference of the  a circular swimming pool is, 88 ft

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
