Answer:

18π $\sqrt{2}$ in

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

d can be calculated as the diagonal d using Pythagoras' identity

d² = 18² + 18² = 324 + 324 = 648 ( take square root of both sides )

d = $\sqrt{648}$ = 18 = $\sqrt{324(2)}$ = 18 $\sqrt{2}$ , thus

C = πd = 18π $\sqrt{2}$

Answer:

18 pi sqrt(2)

Step-by-step explanation:

We know the sides of a Pythagorean triangle

a^2 + a^2 = c^2

18^2 + 18^2 =c^2

2 * 18^2 = c^2

Taking the square root of each side

c = 18 sqrt(2)

This is the diameter of the circle

We want to find the circumference

C = pi * d where d is the diameter

C =pi* 18 sqrt(2)

(02.02 MC) Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflec

Bezzdna [24]

Given:

The vertices of a triangle ABC are A(-2,1), B(-1,4) and C(-4,5).

Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.

To find:

The point B'.

Solution:

If a figure reflected over x-axis, then

$(x,y)\to (x,-y)$

$B(-1,4)\to B_1(-1,-4)$

If a figure reflected over y-axis, then

$(x,y)\to (-x,y)$

$B_1(-1,-4)\to B_2(-(-1),-4)$

$B_1(-1,-4)\to B_2(1,-4)$

If a figure rotated 180 degrees about the origin, then

$(x,y)\to (-x,-y)$

$B_2(1,-4)\to B'(-(1),-(-4))$

$B_2(1,-4)\to B'(-1,4)$

So, the coordinate of point B' are (-1,4).

Therefore, the correct option is A.

Find the area 2 m 4 m 10 m

mina [271]

Answer:

30.285 m²

Step-by-step explanation:

C = 2πr

2 · π · 2

≈ 12.57

12.57 ÷ 2 = 6.285

10 - 2 = 8

8 · 4 ÷ 2

32 ÷ 2

2 · 4 = 8

6.285 + 8 + 16

30.285

Talja [164]

Answer:

The correct result would be f(g) = g * $1 - $50.

Step-by-step explanation:

If you would like to find the function that gives the profit Betty makes by selling a number of glasses of lemonade, you can find this using the following steps:

p ... profit

g ... glasses of lemonade

f(g) = p = g * $1 - $50
