Ascientists makes a 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 pie

The volume of a sphere is given by

If we use , we get

cubic centimeters

So, the volume of 250 spheres is

cubic centimeters

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
