The equation above can be used to calculate the volume V, of a cone with a height h and radius r. If the volume of a cone is 243

WARRIOR [948]

Answer:

The height of the cone is $h=9\ ft$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

In this problem we have

$V=243\pi\ ft^{3}$

$r=h\ ft$

substitute

$243\pi=\frac{1}{3}\pi (h^{2})h$

simplify

$729=(h^{3})$

$h=\sqrt[3]{729}\ ft$

$h=9\ ft$

N − 2/3 = 25 3/4 help now

Sav [38]

Answer:

26 5/12

Step-by-step explanation:

n − 2/3 = 25 3/4 Add 2/3 to both sides

n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine

n = 25 3/4 + 2/3

Work with the fractions

3/4 + 2/3 The lowest common denominator is 12

(3*3)/(3*4) = 9 / 12

(2*4)/(3*4) = 8/ 12

9/12 + 8/12 = 17/12 = 1 5/12

Now you need to add 1 to 25

1 + 25 = 26

And add the fraction 5/12

The answer is 26 5/12

. (02.05 MC) Side AB = 5, side BC = 6, side DE = 5, and side EF = 6. What additional information would you need to prove that ΔA

vaieri [72.5K]

Answer:

Side AC is congruent to side DF

Step-by-step explanation:

We are given that

Side AB=5 cm

BC=6 cm

Side DE=5 cm

Side EF= 6cm

We have to find an additional information would need to prove that $\triangle ABC\cong \triangle DEF$ by SSS.

When two triangles are congruent by SSS it means three sides of one triangle are congruent to corresponding sides of other triangle.

We have in triangle ABC and triangle DEF

$AB\cong DE=5 cm$

$BC\cong EF=6 cm$

$AC\cong DF$

Then , $\triangle ABC\cong \triangle$ DEF

Reason: SSS postulates

Answer: Side AC is congruent to side DF
