The surface area of a cylinder is given by:
A = 2 * pi * r * (r + h)
Where,
r: radio
h: height
Substituting values:
A = 2 * pi * 3 * (3 + 8)
Rewriting:
A = 2 * pi * 3 * (11)
A = 66pi square units
Answer:
A = 66pi square units
39x-3y=21
-3y=21-39x
(subtract both sides of the equation by 39x and divide both sides by -3)
y=-7+3x : would be the equation for y.
Answer:
CIRCLE
Step-by-step explanation:
400+80+13 = 493 is the number.
X+1825=y^2
sqrt（1825）=42.8
so the least is y^2=43^2=1849
so x=1849-1825=24
