A water sprinkler rotates in a circular pattern witha radius of 8 feet. if the sprinkler stops 60 degrees short of completing th
1 answer:
Answer:
B. 8.37 ft
Step-by-step explanation:
⇒This question is on circumference
⇒The water sprinkler covers a circular pattern as it moves to cover 300° and remain with 60° to cover so as to complete a single circular pattern.
⇒The remaining distance asked is the one represented by 60°
⇒Apply the formula for circumference of a circle with angle theta
where alpha is the angle in degrees
Given that r=8ft and ∝=60°
c=3.14×2×8×60°/360°
c=8.37 ft

Answer:
y=25.5
Step-by-step explanation:
To find y, you need to get it by itself. Ask yourself, what is being done to y, then to undo that, do the opposite. For example, if 3 was added to y, you would need to subtract 3 to cancel out the 3. In this case, what is being done to y? It's being divided by 3. So, you multiply by 3 to cancel that out. Whatever you do to one side of an equation, you also have to do to the other. So,
8.5= Multiply both sides by 3
3(8.5) = 3() multiply on the left side, and on the right side the 3s cancel out
25.5=y
