Answer: The angles are 67.5°, 22.5° and 90°.

Step-by-step explanation:

It should be noted that a straight angle is always equal to 180°.

The straight angle is split in the ratio 3:1:4.

The measure of each angle will be:

a. = 3/(3+1+4) × 180°

= 3/8 × 180°

= 67.5°

b. 1/8 × 180° = 22.5°

c. 4/8 × 180° = 90°

The angles are 67.5°, 22.5° and 90°.

David is filling a cylindrical cup with medication for his next patient. If he only fills the cup half way, what is the volume o
nignag [31]

Answer:

Volume of medication in the cup = 50.24 cubic inches

Step-by-step explanation:

Volume of the cylindrical cup = πr^2h

Radius, r = 2 inches

Height, h = 8 inches

Volume of the cylindrical cup = πr^2h

= 3.14 × 2^2 × 8

= 3.14 × 4 × 8

= 100.48

Volume of the cylindrical cup = 100.48 cubic inches

If David only fills the cup half way,

then, the volume of medication in the cup = Total volume of the cylinder / 2

= 100.48 inches / 2

= 50.24 cubic inches

volume of medication in the cup = 50.24 cubic inches
