Find the surface area of a cylinder with a height of 7 m and a base radius of 5 m.
Use the value 3.14 for π, and do not do any rounding.

376.8m

Step-by-step explanation:

Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m

rh = 5m x 7m = 35m while

r^2 = 5m x 5m = 25m

Slot the values into the formula:

V = 2 x 3.14 ( 35) + 2 x 3.14 (25)

V= (6.28 x 35) + (6.28 x 25)

= 219.8 + 157

V= 376.8m

I hope this helps.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
