consider the length of the minute hand the radius of a circle

 the diameter would be 16*2 = 32 inches

 circumference ( distance around the circle) =

PI *32

using 3.14 for PI

3.14 *32 = 100.48 inches  Round the answer as needed

AnnZ [28]

Answer:

The answer to your question is Yes.

Step-by-step explanation:

The math in this problem is that we need to use the Pythagorean theorem to solve it. Pythagorean theorem is part of trigonometry a branch of Maths.

Data

base = 9 ft                      

length = 37 ft

height = ?

Pythagorean theorem

                                     c² = a² + b²

length = c

base = a

height = b

                                   37² = 9² + b²

-Solve for b

                                    b² = 37² - 9²

-Simplify

                                    b² = 1369 - 81

                                    b² = 1288

-Result

                                   b = 35.88

-Conclusion

The ladder will reach a height higher than 35 ft.

Phantasy [73]
If one inch = 2.54 centimeters, then 45 centimeters divided by 2.54 centimeters will give you the amount of inches the piece of wood needs to be.

45/2.54 = 17.72  ---- Rounded to the nearest quarter, would be 17.75 inches.
