A heavy metal sphere

GaryK [48]

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

Combine like terms to simplify the expression: 1.17-0.07a+(-3.92a)

Pachacha [2.7K]

After combining like terms and simplifying $1.17-0.07a+(-3.92a)$ we get $1.17-3.99a$

Step-by-step explanation:

We need to combine like terms to simplify the expression:

$1.17-0.07a+(-3.92a)$

Like terms: The terms are like when they have same variable and same exponent.

Solving:

$1.17-0.07a+(-3.92a)\\=1.17-0.07a-3.92a\\=1.17+(-0.07a-3.92a)\\=1.17+(-3.99a)\\=1.17-3.99a$

So, After combining like terms and simplifying $1.17-0.07a+(-3.92a)$ we get $1.17-3.99a$
