Two spherical balloons are filled with water. The first balloon has a radius of 3 cm, and the second has a radius of 6 cm. How m
Marianna [84]

The volume of water in the larger balloon is 8 times greater than in the smaller balloon

We'll begin by calculating the volume of each balloon.

<h3>For smaller balloon:</h3>
  • Radius (r) = 3 cm
  • Pi (π) = 3.14
  • Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 3³

<h3>V = 113.04 cm³</h3>

<h3>For larger balloon:</h3>
  • Radius (r) = 6 cm
  • Pi (π) = 3.14
  • Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

<h3>V = 904.32 cm³</h3>

Finally, we shall determine how much greater the larger balloon is to the smaller balloon

  • Volume of smaller balloon = 113.04 cm³
  • Volume of larger balloon = 904.32 cm³
  • Greatness =?

Greatness => large / small

Large / small = 904.32 / 113.04

Large / small = 8

Cross multiply

<h3>Large = 8 × small </h3>

Therefore, the larger balloon is 8 times greater than the smaller balloon.

The deepest point in the ocean is 11 km below sea level, deeper than Mt. Everest is tall.
34kurt

The pressure at the depth 11 km below sea level can be calculated using

P=ρgh

P is pressure, ρ is the density of the fluid; g is the gravitational constant, h is the height from the surface, or depth that the object is submerged.

P = ( 1000 kg/ m3) ( 9.81 m.s2)( 11 000m) + 1 atm

P = 107,910,000 pa ( 1 atm/ 101 325 Pa) + 1 atm = 1066 atm
