A pendant is formed using a cylinder and cone. Once assembled, as shown below, the pendant is painted. How many square millimete
solmaris [256]
Surface area of cylinder is given by area of circle + area of the rectangle that curved around the cylinder

Area of the base of the cylinder = \pi r^{2} = 8^{2} \pi =64 \pi
Area of the cylinder 'wall' = width × length = 12×2r \pi=12×16 \pi=192 \pi

Note that the wall of the cylinder is in the shape of a rectangle. The width of the rectangle is the height of the cylinder. The length of the rectangle is the circumference of the circle base.

Surface area of cone is given by \pirl where l is the slanted height of the cone

SA of cone = \pi (8)(10)=80 \pi

Hence total painted surface area is 80 \pi +192 \pi +64 \pi =336 \pi

Write an equation perpendicular to the line y=3/2x-2 that goes through (-4,3)
Goryan [66]

Answer: y=-2/3x-2/3

Step-by-step explanation:

concept to know: two lines that are perpendicular has opposite reciprocal slopes.

y=-2/3x+b

in order to find b or the y-intercept, we need to plug in a point

3=-2/3(-4)+b

3=8/3+b

b=-2/3

y=-2/3x-2/3

Hope this helps!! :)

Help me with number question 7
oksano4ka [1.4K]
Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
 So the three sides of the triangle are
15, 8 and 17
