Answer: h = 9.85 ft

Explanation:

The volume of a cone = 1/3 π r² h

165 = 1/3 π (4)² h

165 = (16/3 π) h

h = 165 ÷ (16/3 π)

h = 9.85 ft

3 * Cone Volume = [PI * radius^2 * height] / 3
height = 3 * Cone Volume / [PI * radius^2]
height = 3 * 165 / [PI * radius^2]
height = 495 / 50.2654824574 
height = 9.8477121038 which rounds to
height = 9.85

Solve for v in terms of s, t, u, and w. wv=uts v=___

laiz [17]

$wv=uts\implies v=\frac{uts}{w}$

we needed to eliminate w, do so by diving both sides by w and obtain the above result :)

Hope this helps.

The diagonals of a rhombus are 14 and 48cm. Find the length of a side of the rhombus.

FromTheMoon [43]

Step-by-step explanation:

Let ABCD be a rhombus. So, AC (AC = 14 cm) and BD (BD=48 cm) will be its diagonals. Let us assume that diagonals are intersecting at point O.

Since, diagonals of a rhombus are perpendicular bisector.

$\because \: OA = \frac{1}{2} \times AC \\ \\ \therefore \: OA = \frac{1}{2} \times 14 \\ \\ \huge \red{ \boxed{\therefore \: OA = 7 \: cm}} \\ \\ \because \: OB = \frac{1}{2} \times BD \\ \\ \therefore \: OB = \frac{1}{2} \times 48 \\ \\ \huge \red{ \boxed{\therefore \: OB = 24 \: cm}} \\ \\ In \: \triangle OAB, \: \: \angle AOB=90° \\ \therefore \: by \: Pythagoras \: Theorem \\ AB= \sqrt{OA^2 +OB^2 } \\ = \sqrt{7^2 +24^2 } \\ = \sqrt{49+576 } \\ = \sqrt{625 } \\ \huge \orange{ \boxed{\ \therefore \:AB= 25 \: cm.}}$

Hence, length of a side (or all) is 25 cm.

Use your knowledge about parentheses and substitution to solve the following:

meriva

Answer:

16. r(s)(t) =

r=2, s=3, t=4

(2)(3)(4)=

(2*3) = 6 ---> 6(4) = 24

final: 24

17. (r)(s)(t)(x)(y) =

r = 2, s = 3, t = 4, x = 5, y = 6

(2)(3)(4)(5)(6)

2*3=6

6*4=24

24*5= 120

120*6=720

final: 720

18. (7x + 2Y) =

x = 5, y = 6

rewrite---> = [7(5) + 2(6)]

[35 + 12] = 47

final: 47

hope this helpsss sorry took a while LOL

Step-by-step explanation:
