In the figure to the right, if AC = 16 and BC = 13, what is the radius? Round to the nearest tenth. (a)  

9.3 units
87 units
9.2 units
3 units

Answer explanation

AB^2 + BC^2 = AC^2

AB^2 + 13^2 = 16^2

AB^2 + 169 = 256

AB^2 = 87

AB = sqrt (87)

AB = 9.327

= 9.3 (rounded to nearest tenth)

DRAG AND DROP QUESTION

Media Image

Determine whether a tangent is shown in the diagram. (a)  

Yes
No

Answer explanation

Converse of Pythagorean Theorem: The line is tangent to the circle if and only if

5^2 + 15^2 = 16^2.

If 5^2 + 15^2 = 16^2, then yes, there is a tangent to the circle.

If 5^2 + 15^2 does not equal 16^2, then no, there is not a tangent to the circle.
