How to we get radius

1 answer:

6 0

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation

3.4x-7.2=5.8x+24 I need help

notka56 [123]

3.4x - 7.2 = 5.8x + 24
3.4 - 5.8x = 24 + 7.2
-2.4x = 31.2
-2.4x / -2.4 = 31.2 / -2.4
x = -13

Gus has a fish tank that holds 47104710 inches^3 3 of water. He is using a cylinder shaped bucket with a radius of 55 inches and

Darya [45]

Answer: 3 times.

Step-by-step explanation:

Here, The Volume of the gas tank = 4710 $in^3$

While, The radius of the cylindrical shaped bucket = 5 in

And, Height of the cylindrical shaped bucket = 20 in

Therefore, The volume of the bucket = $\pi \times r^2\times h$

= 3.14 × 5 × 5 × 20 = 1570

According to the question, cylinder shaped bucket is used to fill the tank.

Thus, The number of times the bucket will be used to fill the tank

= The Volume of the gas tank/ The volume of the bucket = 4710/1570 = 3

Therefore, The bucket will be used three times to fill the tank.

The equation of a parabola is y=x2+6x+9. Write the equation in vertex form.

nignag [31]

Answer:

Step-by-step explanation:

Vertex form is accomplished by completing the square on the quadratic. Do this by first setting the parabola equal to 0 then moving the constant over to the other side:

$x^2+6x=-9$

Now take half the linear term, square it, and add it to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9:

$x^2+6x+9=-9+9$

The reason we do this is to create a perfect square binomial on the left:

$(x+3)^2=0$ (obviously the 0 results from the addition of 9 and -9). Move the 0 back over to the other side and set the quadratic back equal to y:

$(x+3)^2+0=y$

This gives you a vertex of (-3, 0), which is a minimum value, since the parabola opens upwards.
