Answer:

Step-by-step explanation:

If the radius of a cylinder is increased by 20% and its height is decreased by 10%.

To find : What is the percentage change in the volume?

Solution :

Let r be the radius of cylinder is increased by 20%

i.e,

The old radius is 5 and new radius is 6.

Let h be the height of cylinder is increased by 10%

i.e,

The old height is 10 and new height is 11.

The volume of old cylinder with r=5 and h=10

The volume of new cylinder with r=6 and h=11

Volume change is

Percentage change is

Therefore, The percentage change in the volume is 6.4%.

You have a tree in your yard 4 ft to the left of and 5 ft in front of the corner of your porch. A circular fence 3 ft in radius
Natalka [10]

Answer:

(x+4)^2+(y-5)^2=9

Step-by-step explanation:

If the corner of your porch is the origin

  • 4 ft to the left, x=-4
  • 5 ft in front, y=5

The tree's location is at (-4,5).

  • A circular fence 3 ft in radius has its center at the tree(-4,5).

We want to determine the equation of a circle with center (-4,5) and radius 3 ft.

The equation of a circle center (h,k) with a radius of r is given as:

(x-h)^2+(y-k)^2=r^2

(h,k)=(-4,5), r=3

The equation formed by the fence therefore is:

(x-(-4))^2+(y-5)^2=3^2\\\\$Simplifying we obtain:\\\\(x+4)^2+(y-5)^2=9
