Question

Bilal's fishing line was on a spool with a radius of 4 \text{ cm}4 cm. Suddenly, a fish pulled on the line, and the spool spun 1616 times before Bilal began to reel in the fish. What is the distance the fish pulled the fishing line? Round your answer to the nearest \text{cm}cm.

Answer 1

Answer:

402cm

Step-by-step explanation:

First use the formula C=2piR( C= 2pi * Radius)

C=2piR

C=2pi(4)

C=8pi

Then multiply 8pi by the number rotations, 8pi x 16 which is 128pi.

The multiply by pi and round it.

128pi=128 x 3.14= 401.9=

402cm

Answer 2

Question:

Bilal's fishing line was on a spool with a radius of 4 cm. Suddenly, a fish pulled on the line, and the spool spun 16 times before Bilal began to reel in the fish. What is the distance the fish pulled the fishing line? Round your answer to the nearest cm.

Answer:

402 cm

Step-by-step explanation:

Find 1 round:

One round = 2πr

One round = 2π(4) = 8π cm

Find 16 rounds:

1 round = 8π cm

16 rounds = 8π x 16 = 128π = 402 cm (nearest cm)

Answer: 402 cm
