A scientist makes spherical magnets. Each magnet has a radius of 1.02 cm. They are stored away in boxes of 250. Calculate the volume of 250 magnets, to the nearest cubic cm. Use 3.14 for pi

The volume of 250 magnets is 625cm³

Step-by-step explanation:

We know that the formula to calculate the volume of a sphere is

v = 3/4 * π * r³

π = 3.14

r = 1.02cm

we replace the values and calculate the volume of a sphere

v = 3/4 * 3.14 * (1.02cm)³

v = 3/4 * 3.14 * 1.061208cm³

v = 2.49914484cm³

to calculate the volume of 250 spheres we simply multiply by 250

250 * 2.49914484cm³ = 624.78621

if we round to the nearest cubic cm

624.78621cm³ = 625cm³

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
