A and B are two cylinders that are mathematically similar. The area of the cross-section of cylinder is 18 cm squared. Work out the volume of cylinder b.

720 cm³

Step-by-step explanation:

Given 2 similar cylinders withratio of heights = a : b, thenratio of areas = a² : b²Here ratio of heights = 5 : 10 = 1 : 2, thusratio of areas = 1² : 2² = 1 : 4cross section area of B is 4 times cross section area of Across section area of B = 4 × 18 = 72 cm²volume of cylinder = cross section area × heightvolume of cylinder B = 72 × 10 = 720 cm³

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
