Ascientist 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. (v = 4/3 x 3.14 x r^3)

1111 cm³ (to nearest cubic cm)

Step-by-step explanation:

Given that,

radius of spherical magnets a scientist made = 1.02 cm

number of boxes = 250

Use 3.14 for π

Formula for volume of spherical magnets

4/3 x 3.14 x r³

4/3 x 3.14 x (1.02)³

4/3 x 3.14 x (1.061208)³

= 4.443 cm³

The volume of 250 spherical magnets is

  4.443 cm³ * 250

= 1110.7310 cm³

= 1111 cm³(to nearest cubic cm)

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
