Two cylinders are similar. The radius of cylinder A is 5.6 inches. The radius of cylinder B is 1.4 inches. If the height of cyli

natita [175]

The answer is 16 inches.

Let r be a radius and h be a height of a cylinder
Since the cylinders are similar, then the ratio between their radiuses is equal to the ratio of their heights:
r1 : r2 = h1 : h2

Cylinder A:
r1 = 5.6 in
h1 = ?

Cylinder B:
r2 = 1.4 in
h2 = 4 in

5.6 : 1.4 = h1 : 4
h1 = 4 * 5.6 : 1.4
h1 = 16 inches

Answer:

Step-by-step explanation:

We require to find DC

ΔDEC and ΔBAC are similar triangles, hence the ratios of corresponding sides are equal, that is

$\frac{ED}{AB}$ = $\frac{DC}{BC}$ , that is

$\frac{11.5}{23.5}$ = $\frac{DC}{44}$ ( cross- multiply )

23.5DC = 506 ( divide both sides by 23.5 )

DC ≈ 21.532

distance travelled = BC + DC = 44 + 21.532 ≈ 65.5 in → C

Triss [41]

Answer:

x = 6; ∠ONP = 24°

Step-by-step explanation:

1. Find the value of x

$\begin{array}{rcl}\angle MNP & = & \angle MNO + \angle ONP\\3x^{2} + 12 & = & x^{2} + 10x + x^{2} - 2x\\3x^{2} + 12 & = & 2x^{2} + 8x\\x^{2} + 12 & = & 8x\\x^{2} -8x + 12 & = & 0\\(x - 2)(x - 6) & = & 0\\\end{array}$
