Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

$SA = \pi r^{2} + \pi rl$ r = radius of base l = slant height

r = 4.4 and l = 8.1

$SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\$

SA = 3.14(19.36) + 111.9096

= 60.7904 + 111.9096

= 172.70 sq. ft.

What are the parents points for the equation f(x) = 3^x?

ryzh [129]

Answer:

(0, 1) and (1, 2)

Step-by-step explanation:

${ \rm{f(x) = {3}^{x} }}$

• Assume f(x) is one

${ \rm{ {3}^{x} = 1}}$

• Apply logarithms:

${ \rm{x log(3) = log(1) }} \\ \\ { \rm{x = 0 }}$

• Assume f(x) is 2

${ \rm{x = \frac{ log(2) }{ log(3) } }} \\ \\ { \rm{x = 1}}$

Otrada [13]

Answer:

48 inches

Step-by-step explanation:

Given:

A square and an equilateral triangle have the same perimeter

Each side of the triangle is 4 inches longer than each side of the square.

What to find:

What is the perimeter of the square =?

Solution:

Let the side of the square be

Then the side of the triangle will be

The Perimeter of square = Perimeter of an equilateral triangle

Subtracting both sides by

side of the square, = 12 inches

side of triangle will be , 12 + 4 = 16 inches

Now, the perimeter of the square =

Therefore, the perimeter of the square is 48 inches.

and your pfp is so cute!!
