SA=6s^2
SA=384
384=6s^2
divide by 6 both sides
64=s^2
sqrt both sides
8=s

v=s^3
v=8^3
v=512 cubic inches

Answer:

<em> $2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )$ </em>

Step-by-step explanation:

The TSA of the cylinder

$2\pi \: rh + 2\pi {r}^{2}$

In Mathematics, 'is' is =

Twice means 2( )

Product means ×

So we have

$2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )$

If triangle abc is similar to triangle edc find the value of x

svetoff [14.1K]

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{DC}$ = $\frac{AC}{EC}$ , substitute values

$\frac{3x-5}{32}$ = $\frac{5x-5}{56}$ ( cross- multiply )

56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides

168x - 280 = 160x - 160 ( subtract 160x from both sides )

8x - 280 = - 160 ( add 280 to both sides )

8x = 120 ( divide both sides by 8 )

x = 15
