Find the height of a square pyramid that has a volume of 32 cubic feet and a base length of 4 feet. . . . a. 2 feet. b. 4 feet.

Mademuasel [1]

Volume of Pyramid = (1/3)*(base area) * height.

32 ft³ = (1/3)*(4*4)* h. Since Pyramid is square based.

32 = (16/3)*h

16h/3 = 32

h = 32*3/16

h = 6

Height = 6 feet. Option C.

The diagram shows an empty cylindrical container. Ana puts a solid cube of side length 8 cm into the container. She then pours 1

marshall27 [118]

Answer:

<h3><u>Cylinder</u></h3>

$\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

Given:

r = 6 cm

h = 18 cm

$\begin{aligned}\implies \sf V &= \sf \pi (6)^2(18)\\& = \sf 648 \pi \: cm^3\end{aligned}$

$\textsf{Volume of a cube}=\sf x^3\quad\textsf{(where x is the side length)}$

Given:

x = 8 cm

$\begin{aligned}\implies \sf V &= 8^3\\& = \sf 512 \: cm^3\end{aligned}$

<h3><u>Volume available to be filled with water</u></h3>

Volume of cylinder - volume of cube

= 684π - 512

= 1532.75204 cm³

1 litre = 1000 cm³

⇒ 1.5 litres = 1000 × 1.5 = 1500 cm³

As 1500 < 1532.75204, the volume of water poured into the container is smaller than the empty space available in the cylinder. Therefore, the water will <u>not</u> come over the top of the container.

The sum of 3 consecutive odd numbers is 183. what is the second number in this sequence?

Juliette [100K]

Let, the numbers are: x, (x+2), (x+4)
Now, x+x+2+x+4 = 183
3x + 6 = 183
3x = 177
x = 59

So, second number would be: (x+2) = (59+2) = 61

In short, Your Final answer would be 61

Hope this helps!

Mary spent a total of $353.86 for a party. She spent $200.51 on food, plus an additional $30.67 for each hour of the party. How

BartSMP [9]

The party was 5 hours. 353.86-200.51=153.35 then you divide that number by 30.67 and you get 5.
