Answer:Need to convert mph to rpm. How to do it? See below please.

Explanation:

assume statute mile of 5,280 ft or 1760 yards

(

35

m

p

h

60

)

= miles per minute = 0.583333 miles per minute

Now how many ft in 0.58333 miles?

1 mile is 5 280 ft thus

0.58333mile * 5 280 ft/mile = 3 080ft

Circumference of wheel is C=

π

d

C = 26*

π

C

≈

81.681 inches /12 = 6.807ft/revolution

Now how many times does the wheel rotate in one minute?

3

080

f

t

minute

/ 6.807 ft/revolution = 452.489 rpm

A dog is leashed to the corner of a house with a 20 ft long leash. How much running area does the dog have? Round your answer to
11111nata11111 [884]

Answer:

The dog's running area is approximately 942 feet².

Step-by-step explanation:

The dog is leashed to a fixed point, the leash has a length of 20 ft, therefore he can rotate around that point at the maximum distance equal to the length of the leash. This pattern forms a circle, but there is an obstruction, which is the corner of the house. This obstruction takes an arc of the original circle, so the running area of the dog is the area of the whole circle minus the area of the arc formed by the corner of the house.

\text{dog's area} = \text{circle's area} - \text{arc's area}\\\\\text{dog's area} = pi*(20^2) - \frac{90}{360}*pi*(20^2)\\\\\text{dog's area} = \frac{270}{360}*pi*(400)\\\\\text{dog's area} = 942.477\text{ feet}^2

The dog's running area is approximately 942 feet².
