Answer:
Hello! I hope I am correct!
Step-by-step explanation:
295 feet will equal to 89.916 meters.
Steps in order to solve this problem:
First you have to multiply the length in feet by 0.3048.
295x 0.3048 or 295* 0.3048
(295 feet is equivalent to 89.916 meters!)
Will equal 89.916 meters.
Therefore, 295 feet = 89.916 meter
Hope this helps!

Answer:
a) The volume of the sphere is approximately 14,137.16694 which is 14,140 cm³ correct to 4 significant figures
b) The volume of water required to fill the tank is approximately 103,670 cm³
Step-by-step explanation:
a) In the question, the radius of the sphere, r = 15 cm
The formula for the volume, 'V', of a sphere is given as follows;
Where;
r = The radius of the the sphere
V = The volume of the sphere
Plugging in the value for the radius, 'r', of the sphere, in the equation for, 'V', we get;
Therefore;
The volume of the sphere to 4 significant figures is V ≈ 14,140 cm³
b) The parameters of the cylindrical tank are;
The height of the cylindrical tank, h = 60 cm
The radius of the cylindrical tank, r = 25 cm
The volume of a cylinder, V = π·r²·h
∴ The volume of the cylindrical tank without water, '', is given as follows;
= π × (25 cm)² × 60 cm ≈ 117809.72451 cm³
The volume of water, , required to fill the tank with the sphere of volume 'V' placed inside is given as follows
= V +
∴ =
- V
From which we get;
≈ 117809.72451 cm³ - 14,140 cm³ = 103,669.72451 cm³ ≈ 103,670 cm³
The volume of water required to fill the tank, ≈ 103,670 cm³.
