Answer:
172.83 kg
Step-by-step explanation:
A cylindrical container has a radius (r) of 0.3 meter and a height (h) of 0.75 meter and density of 815 kg/m³.
The density of a substance is the mass per unit volume, it is the ratio of the mass of a substance to the volume occupied. The density is given by the formula:
Density = Mass / volume
The volume of a cylinder is given as:
V = πr²h
V = π × (0.3)² × 0.75 = 0.212 m³
Density = Mass/ volume
Mass = Density × Volume
Mass = 815 kg/m³ × 0.212 m³
Mass = 172.83 kg

Hello <span>Vmcdowell43
The word Thanks is a shorter way of saying Thank you. Many people use it because it is easier.
The word yes is a simple way to agree with something.
Hope that helps!

Answer:
121/12
Step-by-step explanation:
1. 11/12 - (-10) = 11/12+10 = 131/12
2. 131/12-5/6 = 131/12 - 10/12 = 121/12
Answer:
Area = 733 m² (to the nearest meter)
Step-by-step explanation:
<u></u>
<u>Formulae</u>
- Circumference of a circle = 2
r - Area of a circle =
r²
(where r is the radius of the circle)
<u>Find the radius</u>
circumference = 96 m
Using the circumference of a circle formula:
⇒ 2
r = 96
⇒
r = 96 ÷ 2 = 48
⇒ r = 48 ÷
= 48/
<u>Find the area</u>
radius r = 48/
Using the area of a circle formula:
⇒ A =
r²
⇒ A =
(48/
)²
⇒ A = 2304/
⇒ A = 733.3859778...
⇒ A = 733 m² (to the nearest meter)
