5y = -3x + 7

y = -3/5x + 7/5

Parallel = same slope

y = -3/5x + b

3 = -3/5 + b, b = 18/5

Standard form: Ax + By = C

y = -3/5x + 18/5

-3/5x - y = -18/5

Multiply by -5

Solution: 3x + 5y = 18

If a cone and sphere have the same radius and the same height, what is the relationship among the volumes of the two shapes?
Korvikt [17]

Answer:

the volume of the sphere will be 4 times the volume of the cone;

Step-by-step explanation:

<u>The question is on volume comparison</u>

Volume of a sphere=4/3 \pi×r³

Volume of a cone= \pi/3×r²h

where r is the radius and h is the height

<u>Apply the condition</u>

If r=h=1 unit

Then volume of sphere will be= 4/3 × \pi×1³ = 4/3\pi

And volume of the cone will be= \pi/3 ×1²×1 =\pi/3

We can see the volume of the sphere will be 4 times the volume of the cone;

4/3\pi = 4×\pi/3
