Let m be the slope and b the y-intercept.
m=(y₂-y₁)/(x₂-x₁)
m= (-1-4)/(-5-(-4))
m= 6
y=mx+b
4=6(-4)+b
b=28
y=6x+28
(-2,4)
parallel means the slopes are the same:
4=6(-2)+b
4=-12+b
b=16
y=6x+16
Hey ! there
Answer:
- Area of circle is <u>8</u><u> </u><u>miles </u><u>square</u>
Step-by-step explanation:
In this question we are provided with a circle <u>having </u><u>radius </u><u>8</u><u> </u>miles . And we are asked to find the <u>area of </u><u>c</u><u>ircle .</u>
For finding area of circle we need to know that what's the formula used for finding area of circle . So ,
<u>Where</u><u> </u><u>,</u>
- π refers to <u>3.</u><u>1</u><u>4</u><u> </u><u>or </u><u>2</u><u>2</u><u>/</u><u>7</u>
- r refers to <u>radius</u><u> of</u><u> circle</u>
<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>
Squaring 8 ,
Multiplying 3.14 and 64 ,
- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>area </u><u>of </u><u>circle </u><u>having </u><u>radius </u><u>8</u><u> </u><u>miles </u><u>is </u><em><u>2</u></em><em><u>0</u></em><em><u>0</u></em><em><u>.</u></em><em><u>9</u></em><em><u>6</u></em><em><u> </u></em><em><u>miles </u></em><em><u>square </u></em><em><u>.</u></em>

Answer:
132cm^3
Step-by-step explanation:
The volume of a cone is 1/3*pi*r^2*h
pi=22/7
r=3
h=14
1/3 * 22/7 * 3^2 * 14 = 132
Answer:
61.74
Step-by-step explanation:
so u start off by solving for ghe semicircles.
the formula I wrote for it was:
1/2(3.14)(3)(3)=14.13
then i multiplied it by 2 because the other semicircle so you get:
28.26
then u find the area of the rectangle and subtract 28.26.
15x6=90
90-28.26=61.74
