Hello!
To find the surface area of a cylinder you use the equation

SA is surface area
r is radius
h is height
PUt in the values you know

Square the number

Multiply 7 and 18

Multiply 126 by 2

Multiply the 49 by 2

Add

The answer is

Hope this helps!
0.5h(115 + 85) = 6550
0.5h(200) = 6550
100h = 6550
h = 655 cms
height is 655 cms
The total length of a line segment is the sum of the lengths of its parts.
MQ = MK + KQ . . . . . . express the relationship between the segments
15 in = 7 in + KQ . . . . . fill in the given information
(15 - 7) in = KQ . . . . . . .subtract 7 in
KQ = 8 in . . . . . . . . . . . simplify
The measurement of KQ is 8 inches.
