Step-by-step explanation:
Answer : The correct option is, (A)
Step-by-step explanation :
First we have to calculate the volume of cylinder.
Formula used:
Volume of cylinder =
where,
r = radius = 3 cm
h = height = 18 cm (We are assuming that 3 solid spheres stacked to each other = 3 × diameter of each sphere = 3 × 2 × 3 = 18)
Volume of cylinder =
Volume of cylinder =
Now we have to calculate the volume of 3 solid spheres.
Formula used:
Volume of 3 spheres =
Volume of 3 spheres =
Volume of 3 spheres =
Volume of 3 spheres =
Now we have to calculate the amount of empty space within a cylinder.
Amount of empty space within a cylinder = Volume of cylinder - Volume of 3 spheres
Amount of empty space within a cylinder =
Amount of empty space within a cylinder =
Therefore, the amount of empty space within a cylinder is,
Answer:
72.5
Step-by-step explanation:
5x5+2x+10=180
1.PEMDAS
2.5x5=25
3.25+10=35
4.Try to get everything away from X so move 35 to other side by subtracting since its a positive number and if negative number (ex. -35) u add, 180-35=145
5. and divide 145 by 2 than finally x is alone which comes out to x=72.5
