The surface area is
A1=7.5*1.5*2=22.5 ft2 top and bottom view
A2=3*1.5*2=9 ft2 laterals view
A3=(7.5*1.5+2.5*1.5)*2=30 ft2 front and rear view
At=22.5+9+30=61.5 ft2
the answer is 61.5 ft2
14 miles.....16hours

Step-by-step explanation:</h2>
A circle is a curve made up of all the points having the same distance from the center. In terms of the diameter, that is any chord that passes through the center, the area can be found as:

We know that
then:

So
is the result and as you can realize this area is in terms of π
What you want to do is convert 20% into a decimal. Then you multiply that by 90. So, if 20% was a decimal(In this case it is 0.2) you do 0.2*90 which equals 18. So the answer is 18.
