5 0

Distributive property.

$a(b+c)=ab+ac$

$(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+ad$

$(a+b+c)(d+e)=a(d+e)+b(d+e)+c(d+e)=ad+ae+bd+be+cd+ce$

and so on.

What is the volume of a sphere with a radius of 1/4

MA_775_DIABLO [31]

What is the volume of a sphere with a radius of 1/4

$\bold{volume \: of \: cube \: = \: \frac{1}{3} \times \pi \times {r}^{3} }$

putting given value in formula

$\implies \: \: \frac{1}{3} \times \frac{22}{7} \times ( \frac{1}{4} ) {}^{3}$

$\implies \: \: \frac{1}{3} \times \frac{22}{7} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4}$

$\implies \: \: \frac{22}{21} \times \frac{1}{64} \\ \\ \implies \: \: \frac{22}{1344}$

$volume \: = \: \frac{22}{1344}$

same can be done while talin pi as 3.14 ..... and you will be able tp get answer as decimal , so lets try that : -

$\implies \: \: \frac{1}{3} \times 3.14 \times ( \frac{1}{4} ) {}^{3} \\ \\ \implies \: \frac{1}{3} \times \frac{1}{64} \times 3.14$

$\implies \: \: \frac{1}{192} \times 3.14$

20 Pts!!! Find the value of AC.

rosijanka [135]

Trianges ACE and FDE are similar, so

$\dfrac{EC}{ED}=\dfrac{AC}{DF}\implies AC=\dfrac{740}{ED}$

D is the midpoint of EC, so ED = 37/2. Then

$AC=\dfrac{740}{\frac{37}2}=40$
