velikii [3]

Answer:

#1: 11 cm

#2: 16.5 in

#3: 2.5 feet

Step-by-step explanation:

#1

P=2l+2w Solve for width by substracting 2l on both sides to isolate 2w

P-2l=2w

or

2w=P-2l

Replace.

2w=26-2(2)\\2w=26-4\\2w=22\\w=\frac{22}{2}\\ w=11cm

----------------------------------------------------------------------------

#2

P=2l+2w

P=2(3.5)+2(4.75)\\P =7+9.5\\P=16.5in

----------------------------------------------------------------------------

#3

P=2l+2w

Solve for l

2l=P-2w\\2l=7-2(1)\\2l=7-2\\2l=5\\l=\frac{5}{2}\\ l=2.5feet

anzhelika [568]

Answer:

\fbox{\begin{minipage}{3.5em}338 (ft)\end{minipage}}

Step-by-step explanation:

The problem could be simplified as following:

Given:

The radius of a circle O is 26 feet.

Solve for:

The length of arc on circle O that measures 13 radians

Solution:

Step 1: Let's find out the correct formula to apply:

The formula to calculate the length of an arc measuring x radians on a circle with radius r feet is:

L = r*x

Step 2: Let's put the data into formula to work out the length L of arc:

L = 26*13 = 338 (ft)

=>  The distance that a horse does on the outer edge travel  when the carousel rotates through 13 radians: L = 338 (ft)

Hope this helps!

:)
