The answer is pi.
to find this, you find the circumference of a circle with a 4m radius, which is 2pi(4) or 8pi. then you need find the fraction of the circle that this angle is. a circle is 360degrees, so 45/360 is 1/8.

1/8 x 8pi = pi -> pi m

Answer:

pi

Step-by-step explanation:

First find the circumference of a circle with radius 4

C = 2 * pi *r

C = 2*pi*4

C = 8pi

A circle has 360 degrees

Find the fraction of a circle that 45 degrees is

45/360 = 1/8

Multiply the fraction by the circumference

1/8 *8pi = pi

Why do whole numbers with an exponent get bigger while fractions with an exponent get smaller.
ohaa [14]

Raising a whole number to a power means: 

             Take (a number of things) a number of times, and then possibly
             take that big number of things a number of times again.

Raising a fraction to an exponent means: 

             Take a piece of (a piece of one thing), and then possibly
              take just a piece of that smaller piece.

Justin is on a road trip. Over the past two days, he’s driven a total distance of 504 miles at an average speed of 56 miles/hour
irakobra [83]
Recall d  = rt, distance = rate * time.

now, he has a speed rate of 56 mph for a distance of 504

\bf d=rt\implies 504=56t\implies \cfrac{504}{56}=t\implies \stackrel{hours}{9}=t

so, at that speed the whole driving time is 9 hours then.  Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.

how many miles is it for 7 hours at 56mph?  d = rt ---> d = 56 * 7

that many miles he drove yesterday.

If the diagonal of a square is 11.3 meters, approximately what is the perimeter of the square?
Stells [14]

Answer:

32

Step-by-step explanation:

The diagonal of a square has a length of x sqrt(2), where x is the side length. This means the perimeter of the square is 4 (11.3/sqrt(2)), which means the perimeter is approx. 4*8, which is 32
