I think you are referring to this:
The volume of the sink shaped like a half sphere is [2000/3] π in^2.

A. The volume of a cylinder =area of the base * height
For this part the cup has a diameter, d, of 4 in and height, h, of 8 in.
[2000 / 3]π / [32π] = 20.83
Answer: 21 cups.

B. For this part the diameter of the cup is 8 in and the height is 8 in
And the number of cups needed is [2000π/3] / (128π) = 5.2
Answer: 5 cups

Please help me with this problem

Answer:

<em>The measures of angles A, B, and C are respectively 21°, 125°, and 34°</em>

Step-by-step explanation:

<u>Equations</u>

We are given some conditions applying to the internal angles on a triangle ABC.

The measure of angle A is 13 less than the measure of angle C.

The measure of angle B is 11 less than 4 times the measure of angle C

Let x = measure of angle C

The first conditions states:

$m\angle A = x-13$

The second conditions states:

$m\angle B = 4x-11$

The sum of all angles must be 180°, thus:

$x - 13 + 4x - 11 + x = 180$

Simplifying:

6x -24 = 180

Adding 24:

6x = 204

Dividing by 6:

x = 204/6

x = 34

$m\angle C = x = 34^\circ$

$m\angle B = 4x-11 = 4*34-11 = 125^\circ$

$m\angle A = x - 13 = 34 - 13 = 21^\circ$

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

A rectangular poster is 5 dm long and 3 dm wide. Sara wants to paint the whole poster. Find the area of the poster in square cm.

Zina [86]

Answer:

$\boxed{1500cm^{2} }$

Step-by-step explanation:

Area = Length × Width

→ Identify the length and width

Length = 5 and Width = 3

→ Substitute in the values

Area = 5 dm × 3 dm

→ Convert into cm

Area = 50 cm × 30 cm

→ Simplify

1500 cm²
