To get perimeter you add all the sides together. You have 2 sides of 10ft, one side of 8ft and then the half circle. To find the arc length of the half circle you would do 1/2(2πr) which would give you πr. R=4ft since the diameter is 8ft. So you would add 8,10,10 and 4pi. If it wants an exact answer it would be 28+4pi. If it wants an approximate answer it would be 40.6ft
44 feet. 3600 seconds. 1 mile

1 second 1 hour. 5280 feet
I wrote it this way so the units cancel out. You are multiplying the fractions by each other
The car is going 30 mph, and will go 120 miles in 4 hours.
Formula:
(3.14)r^2
Larger one:
(3.14)(3)^2
28.26 * 13
367.38 in^2
Smaller one:
(3.14)(3)^2
28.26 * 8
226.08 in^2
The correct answer is: 3) " <span>20w⁵ </span>" .
__________________________________________
Explanation:
_________________________________________
(10w³)²<span>/ (5w) =
[ 10</span>² * w⁽³*²)<span> ] / [5w] =
(100* w</span>⁶) / 5w =
(100/5) * w⁽⁶⁻¹⁾ =
20 * w⁵ =
20w⁵ ; which is: Answer choice: 3) " <span>20w⁵ </span>" .
