Answer:

It will be worth $128.

Step-by-step explanation:

After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

To the nearest tenth, find the volume of a sphere with a diameter of 36 cm. Use 3.14
lesya [120]

Answer:

The volume of the sphere is 24416.6 cm³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

v = volume

r = radius

v = ⁴⁄₃πr³.

To solve this formula we first have to have all the data, as we see we need to calculate the radius, which is calculated by dividing the diameter by 2

r = d/2

r = 36cm/2

r = 18cm

Now that we have all the data we can solve the formula

v = ⁴⁄₃πr³.

v = ⁴⁄₃ * 3.14 * (18cm)³

v = 24416.64 cm³

Round to the nearest tenth

v = 24416.6 cm³
