<h2>Answer:</h2>
D. Distance formula
<h2>Step-by-step explanation:</h2>As in the statement:
<em>The distance form</em> to
is
<em>whose justification is the </em><em>Distance Formula. </em>
<em />
Here in this statement the justification is also the Distance Fromula, so we take the distance from whose result is also 2 and is the radius of the circle.
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
