Volume of Sphere

6231 spheres can be made from 1 kg of lead

Step-by-step explanation:

Given Density of lead d = 11.35 gm/cm³

Let the maximum number of spheres that can be made with 1 kg of lead = n

Radius of sphere r = 1.5 mm = 0.15 cm

Volume of Sphere = 4/3  \pi  r^{3} \\

Volume of one sphere V = (4/3) * 22.7 * r³

Volume of n spheres = n * (4/3) * 22.7 *r³    ….. Eq (1)

Total mass of lead m = 1kg = 1000gm ...Eq (2)

Equating the above two equations

n × V × d = m

n × (4/3) × 22.7 × ( 0.15 )³ = 1000

Therefore calculating n= 6231.45

But considering the whole number, 6231 spheres can be made from 1 kg of lead.

Jeff takes 20 minutes to jog around the race course one time, and 25 minutes to jog around a second time. What is his average sp
aksik [14]
Distance = rate*time 
distance/time = rate

The race course is 3 miles around and Jeff does it twice, so the distance he goes = 2*3 miles = 6 miles. 

 He takes 20 minutes to go around once and 25 minutes to go around the second time, so the total time = 20 min + 25 min = 45 min. 

His speed is miles per hour, not miles per minute, so convert 45 minutes to a hours:
 45 min/60 min = 0.75 hours <span>distance/time = rate = 6 miles/0.75 hours = 8 mph</span>
