Bonjour écrit moi en français je n’ai pas compris mais c un travail de cm1
<em>Answer:</em>
<em>Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.</em>

Answer:
16 pi ft^2
Step-by-step explanation:
C = 2 * pi *r
4 pi = 2* pi *r
Divide each side by 2pi
4pi/2pi = 2pi r/2pi
2 = r
We can find the surface area
SA = 4 pi r^2
= 4 * pi * (2)^2
= 16 pi ft^2
A perpendicular line will have a slope that is the negative reciprocal of the other.
Since the slope of this equation is 0.25, or 1/4, then the negative reciprocal of this is -4/1, or -4. Since this line has to pass through (-6,8), the y-intercept of the equation is -16. Then the equation is y = -4x - 16. Hope this helps!
