two circles are externally tangent to each other. One circle has a diameter of 62 yards and the distance between the centers of
the two circles is 85 yards. What is the diameter of the other crop circle
1 answer:
Answer:
108 yards
Step-by-step explanation:
Let circle A be the circle with the 62 yard diameter
Let circle B be the circle whose diameter we are trying to solve for.
- Externally tangent circles are circles which touch each other and share a common external tangent.
- Circle A has a tangent of 62 yards and thus a radius ( half the diameter) of 31 yards.
- The distance between the centers of the 2 circles is 85 yards. If you subtract the radius ( distance from the center of the circle to its circumference) of circle A then we'll only be left with the radius of circle B.
- 85 - 31= 54 yards which is the radius of circle B
- To get the diameter: 54 x 2 = 108 yards

First recognize that the unit rate we're finding is gallons per hour, or 
.
rate for Tank 1 = x gallons per hour = <em>a</em> gallons / <em>b</em> hours
rate for Tank 2 = y gallons per hour = <em>c</em> gallons / <em>d</em> hours
rate for Tank 1 = x gallons per hour = <em>a</em> gallons / <em>b</em> hours
rate for Tank 2 = y gallons per hour = <em>c</em> gallons / <em>d</em> hours
