Find the volume of it​

946.808 cm²

Step-by-step explanation:

The figure is made up of a cone and a hemisphere.

Volume of a cone is given as;

V_c = ⅓πr²h

Volume of a hemisphere is given as;

V_h = ⅔πr³

In the figure, radius of hemisphere is 6.

Thus; V_h = ⅔π × 6³ = 452.389 cm²

For the cone, height is not given but we can find it from pythagoras theorem.

h = √(6² + (2√(34))²

h = √(36 + (4 × 34))

h = √(172)

Thus;

V_c = ⅓π × 6² × √(172)

V_c = 494.419 cm²

Total area = V_c + V_h = 494.419 + 452.389 = 946.808 cm²

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: the correct answer is -32
