A heavy metal sphere

Mathematics
1 answer:
GaryK [48]3 years ago
7 0

Answer: the height of the water after the sphere is placed in

it is 33.33 cm

Step-by-step explanation:

The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as

Volume = πr^2h

Where

π is a constant whose value is 3.14

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

r = 10 cm

h = height of water in the cylinder = 20 cm

Volume of water in the cylinder before the sphere was placed in it would be

V = 3.14 × 10^2 × 20 = 6280 cm^3

The formula for determining the volume of the sphere is expressed as

Volume = 4/3 πr^3

V = 4/3 × 3.14 × 10^3 = 4186.67cm^3

Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2

To determine the new height of the water,

10466.67 = 3.14 × 10^2× h

h = 10466.67/314 = 33.33 cm

If m angle acd = 120- x, m angle b = 60, and m angle a = 10 + x, find m angle acb
lesya [120]

Answer:

ACB = 85

Step-by-step explanation:

First find x:

10+ x + 60 = 120 - x

x + 70 = 120 - x

Add x to both sides

2x + 70 = 120

subtract 70 from 120

2x = 50

Divide 2 from both sides

x = 25

10 + 25 + 60 = 95

Subtract 95 from 180

ACD = 85
