a sphere with a radius of 15cm has the same volume as a cylinder with a radius of 5 cm.what is the height od the cylinder
damaskus [11]

Answer:

180cm

Step-by-step explanation:

Vol of sphere = (4/3) pi r^3 and vol of cylinder = pi r^2 h

so

(4/3) pi 15^3 = pi (5)^2 h

(4/3) * 15^3 = 25h

h =  [(4/3) * 15^3 ] / 25  =  180 cm

A leaking pond looses 18 gallons of water in 34 hours , how many gallons will be left after 41 hours
Ann [662]

The amount of water left = 21.3 gallons.

We have a leaking pond which looses 18 gallons of water in 34 hour.

We have to determine how many gallons of water will be left after 41 hours.

<h3>What do you understand by gallon?</h3>

The gallon is a unit of volume in imperial units and United States customary units.

I gallon = 231 cubic inches = 3.785411784 liters.

According to question, we have -

Amount of water lost by the pond in 34 hours = 18 gallons

Therefore -

Amount of water lost by the pond in 1 hour = \frac{18}{34}

So, the amount of water loosed by the pond in 41 hours = \frac{18}{34}\times 41  = 21.3

Hence, the amount of water left = 21.3 gallons.

Answer:

A. 3x^2+7x^2+2×3x ×7-84x = 3x^2+7x^2-2×3x×7

9x^2+49x^2+42x-84 x= 9x^2+49x^2-42x

9x^2+49x^2-42 = 9x^2+49 x^2-42x
