Answer:
6.3 feet
Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
a² + 3² = 7²
a² + 9 = 49

a² = 40
Take the square root of both sides
a = 6.324555320336759
Rounded
a = 6.3

A diameter is a straight line that touches 2 points on the circumference of a circle and touches the point at the center. <em>KA</em> is the diameter.
A radius is a straight line touches a point on the circumference of a circle and touches the point at the center. <em>BE</em> is the radius.
