Find the height of a cylinder whose volume is 1.54 m³ and diameter of base is 140 cm

1 m

Step-by-step explanation:

diameter of base = 140 cm

so, radius = 70 cm

Given,

Volume of the cylinder=1.54

Diameter of the base=140

Radius of the base==70 =0.7

Height=

We know,

Volume of cylinder=

or,1.54=

or,1.54=

or,1=h

Therefore,The height of the cylinder is 1m.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
