A Student said the volume of a cylinder with a 3-inch diameter is two times the volume of a cylinder with the same height and a

1.5-inch radius. What is the error?

They would be the same because the formula is volume equals pi radius squared times height. So you would use the radius of 1.5 instead of the diameter of 3

Elanso [62]

Answer:

Solution given:

2:centroid=\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3}

=\frac{1+3+5}{3},\frac{2+7+3}{3}=(3,4)

4:

Slope:\frac{y_2-y_1}{x_2-x_1}=\frac{6-2}{5-3}=2

3;

perpendicular distance =\frac{ax_1+by_1+c}{\sqrt{a²+b²}}

(x_1,y_1)=(3,-2)

4x-3y+2=0

comparing above equation with ax+by+c =0 ,we get

a=4

b=-3

c=2

d=\frac{4*3+(-3*-2)+2}{\sqrt{4²+(-3)²}}

=4 units

(2,4);slope=1/2<br><br> (-8,-1);slope=-3/4
igomit [66]

Answer:

Step-by-step explanation:

1. y - 4 = 1/2(x - 2)

  y - 4 = 1/2x - 1

  y = 1/2x + 3

2. y + 1 = -3/4(x + 8)

   y + 1 = -3/4x - 6

  y = -3/4x - 7

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Viktor [21]

Answer:

Step-by-step explanation:

Triangle IJK is a right angle triangle.

From the given right angle triangle

JK represents the hypotenuse of the right angle triangle.

With ∠K as the reference angle,

IK represents the adjacent side of the right angle triangle.

IJ represents the opposite side of the right angle triangle.

To determine Cos K, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse. Therefore,

Cos K = 36/85

Cos K = 0.4235

Rounding up to the nearest hundredth,

Cos K = 0.42
