The volume of a sphere is a function of its radius. V equals 4 over 3 πr cubed . Evaluate the function for the volume of a volle

Nataly_w [17]

Answer:

The answer to your questin is: V = 5276.7 cm³

Step-by-step explanation:

Data

radius = 10.8 cm

Volume = ?

Formula

$V = \frac{4}{3} \pi r^{3}$

$V = \frac{4}{3} \pi (10.8)^{3}$

V = 5276.7 cm³

A wall 15 m long, 30 cm wide and 4 m high is made of bricks, each measuring

schepotkina [342]

L = 15m = 1500cm
b= 30cm
h= 4m= 400cm

So, total volume of the wall= l×b×h
= 1500×30×400= 1,80,00,000 cm^3

Now, volume of one brick= 22×12.5×7.5= 2062.5 cm^3

Volume of wall containing only bricks= total volume of the wall - volume of wall containing mortar
= 1,80,00,000 - (1,80,00,000 × 1/12)
= 1,65,00,000 cm^3

So, no. of bricks = volume of wall containing bricks ÷ volume of one brick
= 1,65,00,000 ÷ 2062.5
= 8000 bricks.

Somebody had a seizure while making this question, please help

Check the picture below.

$\textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}asn ~~ \begin{cases} a=apothem\\ n=\stackrel{side's}{number}\\ s=\stackrel{side's}{length}\\[-0.5em] \hrulefill\\ a=7\\ s=8.1\\ n=6 \end{cases}\implies \stackrel{\textit{area of the hexagonal base}}{A=\cfrac{1}{2}(7)(8.1)(6)} \\\\[-0.35em] ~\dotfill$

$\textit{volume of a prism}\\\\ V=Bh ~~ \begin{cases} B=\stackrel{base's}{area}\\ h=height\\[-0.5em] \hrulefill\\ B=\frac{1}{2}(7)(8.1)(6)\\ V=3572.1 \end{cases}\implies 3572.1=\cfrac{1}{2}(7)(8.1)(6)h \\\\\\ 3572.1=170.1h\implies \cfrac{3572.1}{170.1}=h\implies \boxed{21=h}$

well, the length of the tunnel is "h", now two 8 meters cars, that's 8+8=16 meters plus a 3 meter connector between them, that's 16 + 3 = 19 meters, can those two cars connected like so fit inside the tunnel? sure thing, "h" can fit 19 meters just fine.
