If DA = 6 and MD = 4, what is the length of DK?

Leto [7]

Answer:

DK = 9

Step-by-step explanation:

In triangle AMD,

h² = p² + b²

or, h² = 6² + 4²

or, h²= 36 + 16

so, h² = 52

so, AM² = 52

Take x as reference angle,

cos²x = 16/52

Now,

In triangle, AMK,

Taking x as reference angle,

cos²x = b²/h²

cos²x = AM²/MK²

or, cos²x = 52/MK²

Now,

cos²x = 16/52 = 52/MK²

or,

16/52 = 52/MK²

or, 16MK² = 2704

or, MK² = 2704/16

or, MK² = 169

so, MK = 13

Now,

DK = MK - MD

or, DK = 13 - 4

so, DK = 9

Answer:

33.49 mm³

Step-by-step explanation:

The formula of volume of sphere

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

The volume of the sphere

$= \frac{4}{3} \times 3.14 \times {2}^{3}$

$= \frac{100.48}{3}$

$= 33.4933333...$

= 33.49 mm³ (rounded to the nearest hundredth)
