Since the focus and vertex are above and below each other, rather than side by side, I know that this ellipse must be taller than it is wide.

Then

a² will go with the y part of the equation

Also, since the focus is 8 units below the center, then c = 8

since the vertex is 17 units above, then a = 17

The equation b² = a² – c² gives me

b²=17²-8²-----> b²=225

the equation is

y²/a²+x²/b²=1------> y²/289+x²/225=1

the answer is

y²/289+x²/225=1

Help pleaseeeeee thanks i hope u have a good day

VikaD [51]

Answer:

12825$

Step-by-step explanation:

1 yard = 3 ft

we can convert each of the lengths from ft to yards

240 ft = 80 yards

285 ft = 95 yards

450 ft = 150 yards

150+150+95+80 = 475 yards

1 yard of fencing costs 27$ so we are going to multiply that by the total yards

475*27=12825$

Find the volume of this cylinder. give your answer to 1 decimal place base is 11cm. length is 14cm

nlexa [21]

Answer:

Volume = 1330.6cm³

Step-by-step explanation:

Step one

This problem bothers on the mensuration of solid shapes a cylinder.

We know that the volume of a cylinder is expressed as

V= πr²h

Step two

Given data

Base of the cylinder /diameter = 11cm

Hence radius = 11/2= 5.5cm

Length /height of cylinder = 14cm

Step three

Substituting our given data we have

Volume = 3.142*(5.5)²*14

Volume = 3.142*30.25*14

Volume = 1330.637cm³

to 1 decimal place we have

Volume = 1330.6cm³
