SA =207.24 in ^2

Step-by-step explanation:

S  A  = 2 π r h + 2 π r^ 2

we know the diameter is 6 so the radius is 1/2 the diameter so it is 3

r=3

h = 8

S  A  = 2 π r h + 2 π r^ 2

SA = 2 * pi * 3 * 8 + 2 * pi * 3^2

SA = 48 * pi + 2* pi *9

SA = 48*pi + 18*pi

SA = 66 * pi

pi is approximated by 3.14

SA = 66* 3.14

SA =207.24 in ^2

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
