What is the total surface area of a cylinder whose length is twice the radius

lianna [129]

Lateral surface area of a cylinder: 2πrh, r is the radius, h is the height.
area of the top and bottom circle: πr²
when h=2r, the total surface area is:
2πr(2r)+πr²+πr²=6πr²
the answer is 6πr²

What would be the slope for (-4,-7) (-6,4)

Sliva [168]

Answer: $\frac{11}{-2}$

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

$\frac{y2-y1}{x2-x1} =$ m

so when using that formula with the cords, you get

$\frac{4-(-7)}{-6-(-4)}$

and then subtract everything and you'll get

$\frac{11}{-2}$

The sides of a rectangle in the coordinate plane are parallel to the axes two of the vertices of the rectangle are (3,-2) and (-

Llana [10]

Answer:

C(-4,-2), D(3,-7)

$Ar=35unit^{2}$

Step-by-step explanation:

we procced to identify points:

A(-4,-7), B(3,-2)

for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)

C(-4,-2), D(3,-7); Area of the rectangle Ar=b*h, where

$b=(X_{D}-X_{A}); h=(Y_{B}-Y_{D})$

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5= $35unit^{2}$
