If BD = 9 and AD = 13, AB = ?
| 11 | |
| 7 | |
| 4 | |
| 2 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhat is the circumference of a circle with a diameter of 7?
| 8π | |
| 6π | |
| 9π | |
| 7π |
The formula for circumference is circle diameter x π:
c = πd
c = 7π
If side a = 2, side b = 9, what is the length of the hypotenuse of this right triangle?
| \( \sqrt{45} \) | |
| \( \sqrt{10} \) | |
| \( \sqrt{52} \) | |
| \( \sqrt{85} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 22 + 92
c2 = 4 + 81
c2 = 85
c = \( \sqrt{85} \)
