A regular pentagon with a perimeter of 10 cm is dilated by a scale factor of 3/2 to create a new pentagon. What is the the perim

Doss [256]

Given:

Perimeter of a regular pentagon = 10 cm

The pentagon is dilated by a scale factor = $\dfrac{3}{2}$ .

To find:

The perimeter of the new pentagon.

Solution:

If a figure is dilated by a scale factor <em>k</em>, then

Perimeter of new figure = <em>k</em> × perimeter of original figure

The scale factor is $\dfrac{3}{2}$ and the perimeter of a regular pentagon is 10 cm. So, the perimeter of a new pentagon is:

$\text{Perimeter of new pentagon}=\dfrac{3}{2}\times 10$

$\text{Perimeter of new pentagon}=3\times 5$

$\text{Perimeter of new pentagon}=15$

Therefore, the perimeter of the new pentagon is 15 cm.

Sandy wants to cover a wooden cylinder with a diameter of 1 ft and a height of 4 ft with carpet to build a scratching post for h

aleksley [76]

Answer:

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats

Step-by-step explanation:

Sandy needs to calculate the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=2\pi r^{2}+2\pi r(h)$

we have

$r=1/2=0.5\ ft$ ----> the radius is half the diameter

$h=4\ ft$

assume

$\pi =3.14$

substitute the values

$SA=2(3.14)(0.5)^{2}+2(3.14)(0.5)(4)$

$SA=14.13\ ft^{2}$

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats
