Formula for the surface area of a cylinder: 2 x pi x r^2 + 2 x pi x r x h
Radius (r) = 3
Height (h) = 3
2 x pi x 3^2 + 2 x pi x 3 x 3
2 x pi x 9 + 2 x pi x 9
18pi + 18pi
36pi = 113.1 cm^2
Hope this helps!
Points A, B, and C lie on a line.
Point A is between points B and C.
Starting at point A and going past point B, you have ray AB.
Starting at point A and going past point C, you have ray AC.
If you think of angle BAC, it is a straight angle of 180 degrees.
You have the two rays AB and AC forming a line and an angle.
Answer:
56
Step-by-step explanation:
Just substitute 7 for p in the expression 9p - 7: 9(7) - 7 = 56
Answer:
Explained
Step-by-step explanation:
average speed from Tallahassee to Gainesville is 30miles/hour
and the total average speed of the whole trip is 40 miles/hour
let the average speed in return journey be x miles per hour.
we know that if the distance is constant the average speed of the whole trip is given as


on calculating we get x= 60 miles/hour
now, since the distance between two places is always constant, the result does not matter on the distance between two places. The average speed will remain the same.
