A circle has a circumference of 1 ,017.36 What is the radius of the circle?

162 units

Step-by-step explanation:

Let the radius of the circle be r units

circumference of the circle=1017.36

=>2πr=1017.36

=>2(3.14) r=1017.36

=>6.28 r=1017.36

=>r=1017.36/6.28

=>r=162 units

536

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
