What is the distance the hula hoop rolls in 4 full rotations?

879.65

Step-by-step explanation:

Givens

r = 35 cm

pi = 3.14

Formula

Circumference = 2*pi*r

Solve for 1 loop

C = 2*pi * r

C = 2 * 3.14 * 35

C = 219.9 cm for 1 loop

Solve for 4 loops

1 loop gives 219.9 cm distance that will be covered.

4 loops = x

1/4 = 219.9/ x       Cross multiply

x = 4 * 219.9         Combine on the right.

x = 879.65 cm

the correct answers i think are b. and d.

give me brainliest if it is correct!

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
