<h2>Answer:</h2>

The radius of the cone is:

          r=\dfrac{2}{\sqrt{\pi}}

<h2>Step-by-step explanation:</h2>

The total area of cone is given by:

T.A.=\pi r(l+r)=\pi rl+\pi r^2=12---------(1)

where r is the radius of the cone and l is the slant height of the cone.

and the lateral area of cone is given by:

L.A.=\pi rl=8---------(2)

Hence, from equation (1) and (2) we have:

 8+\pi r^2=12\\\\\\i.e.\\\\\\\pi r^2=4

i.e.

r^2=\dfrac{4}{\pi}

i.e.

r=\dfrac{2}{\sqrt{\pi}}

Farmer Ed has 550 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fenc
ss7ja [257]
Let width of the rectangular plot be x meters

then total of widths = 2x 
and the length would be (550 - 2x) meters.

so the area = x(550 - 2x)  = 550x - 2x^2

to find the maximum are find the derivative and equate to zero:-

f'(x) =  550 - 4x = 0
x = 550/4 =  137.5 meters = width

length = 550 - 2(137.5) = 275

Maximum area  is when width = 137.5m and length = 275m

when your finding the area of a rectangle do you multiply the numbers around the perimeter or add them.
Flura [38]
When you are finding the area, you multiply the length x the width. So for example, we have a rectangle that the length is 6 feet and the width is 4 feet. So, first of all we multiply 6x4= 24. Since its area don't forget it is Square Feet (or any other type of measurement).

Hope it helps!

Can Someone please explain also
IRINA_888 [86]

Answer:

y = 1/4x -10

Step-by-step explanation:

The equation would be y = 1/4x -10

we know that we have to set the equation up as y=mx+b

m being slope and b being y-intercept

we can see on the graph that the line intercepts the y-axis at -10, so that would be b

for slope, you can just look and count rise over run so:

it goes 10 up and 40 over which equals 10/40 also known as 1/4

hope that helped :)
