A barrel shaped like a cylinder is laid on its side and rolled up a ramp. The barrel has a circular base that is 0.5 m in diameter. If the barrel turns 38 times in being rolled up the ramp, how long is the ramp? Use the value 3,14 for \( \pi \). Round your answer to the nearest tenth. Do not round any intermediate steps. m

To find the length of the ramp, we first need to calculate the circumference of the barrel. The formula for the circumference (C) of a circle is: \[ C = \pi \times d \] where \( d \) is the diameter. Given that the diameter of the barrel is 0.5 m, we can substitute it in: \[ C = 3.14 \times 0.5 = 1.57 \text{ m} \] Now, since the barrel makes 38 complete turns while rolling up the ramp, the total distance rolled (which is the length of the ramp) is calculated by multiplying the circumference by the number of turns: \[ \text{Length of the ramp} = C \times \text{Number of turns} \] Substituting the values we have: \[ \text{Length of the ramp} = 1.57 \text{ m} \times 38 = 59.66 \text{ m} \] Rounding to the nearest tenth, the length of the ramp is: \[ \text{Length of the ramp} \approx 59.7 \text{ m} \] So, the ramp is approximately 59.7 m long.
