Find the volume of a cone with a height of 7yd and a base diameter of 6yd . use the value 3.14 for π , and do not do any roundin
yarga [219]
I think the volume of the cone is 65.94yd because the radius is 3 and the height is 7 also 3 to the second power equals 9 then 3.14 multiplied by 9 equals 28.26 and finally 28.26 multiplied by 7/3 equals 65.94

V=3.14 x r^2 h/3
V=3.14 x 3^2 7/3

larisa [96]

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2.  (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± \sqrt{b^{2}-4ac } / 2a

Substitute in:

-6 ±\sqrt{7^{2} -4(2)(6)} / 2(2)

-6±\sqrt{49 - 48} / 4

Both forms:

-6 + \sqrt{1} / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75
