Answer:
<em>Length of arc: 6π</em>
Step-by-step explanation:
<em>~ Let us answer this question in terms of π, remaining so ~</em>
1. Assume that this is a complete circle, for the moment being. The chord with length of 12 units would act as the diameter, and using that information we could determine the circumference of this complete circle...which will help us in the future. Apply the formula π * d as such: π * 12 ⇒ 12π to get the circumference as 12π.
2. Knowing that the length of the complete circle's circumference is 12π, this arc is part of a semicircle, meaning that it's value would be half of that of the complete circle's circumference, or in other words: 12π/2 ⇒ <em>Answer ~ Length of arc: 6π</em>
Answer: 38 feet
Step-by-step explanation:
Based on the dimensions of the garden, we can infer that it a rectangular garden because one side is longer than the other.
The perimeter of a rectangle is calculated as:
= (2 * length) + (2 * width)
= (2 * 15) + (2 * 4)
= 30 + 8
= 38 feet
I think it is b but wait till someone else answers to
Step-by-step explanation:
let X = speed of slow bicycle rider
2x=speed of fast bicycle rider
3(x+2x)=72
X=8mph(slowest bicycle rider)
2x=16mph(fastest bicycle rider)
