Answer:

m∠KIJ = m∠LIM ⇒ answer B

Step-by-step explanation:

* Lets explain how to solve the problem

∵ I is the mid-point of NH

∴ IN = IH

- MJ is perpendicular to NH and passes through I the mid-point of NH

∴ MJ is perpendicular bisector of NH

- NH ⊥ MJ and intersects it at I

∴ m∠NIM = m∠NIJ = 90°

- ∠ NIM consists of two angles ∠NIL and ∠MIL

∵ m∠NIM = m∠NIL + m∠MIL

- ∠NIJ consists of two angles ∠NIK and ∠JIK

∵ m∠NIJ = m∠NIK + m∠JIK

∴ m∠NIL + m∠MIL = m∠NIK + m∠JIK ⇒ (1)

∵ NH bisects ∠KIL

∴ m∠NIL = m∠NIK ⇒ (2)

- From (1) and (2)

∴ m∠MIL = m∠JIK

* m∠KIJ = m∠LIM

If the sphere has a radius of 18 units, then what is the approximate volume of the sphere? Use 3.14 for the value of π and round
Art [367]
The formula for volume of a sphere is V=4/3πr^3.
If we substitute 18 in for "r", we can work the problem out from there.

V = 4/3(3.14)(18)^3
V = 24,416.64 cubic units, so your answer will be C.

Hope that helps!

!!!The volume of the given figure is______!!!!
choli [55]

Answer:

284.837734 ft^3 rounded up to 284.84 ft^3

Step-by-step explanation:

Cylinder Volume: pi*r^2h

pi*4^2*4=201.06193

Cone Volume: pi*r^2*(h/3)

pi*4^2*(5/3)=83.7758041

201.06193+83.7758041=284.837734

284.837734 ft^3
