Answer:
3.14 ft² or 2,917 cm²
Step-by-step explanation:
To do this, we need to know the expression to calculate the area of a circle.
The area of any circle is:
A = πr²
Where:
π: value of pi, which is 3.14
r: radius of the circle, in this case 1 ft
Calculating the area in units of ft:
A = 3.14 * (1)²
A = 3.14 ft²
Now, if you convert the foot to cm we have:
1 * 30.48 = 30.48 cm
Solvinf for A:
A = 3.14 * (30.48)²
A = 2,917.15 cm²
Answer:
Step-by-step explanation:
The volume of a cylinder is expressed as
V = πr^2h
Where
π is a constant
h is the height of the cylinder
The volume of a cone is expressed as
V = 1/3πr^2h
Where
π is a constant
h is the height of the cone
If the cylinder and a cone have congruent bases and the same volume, it means that
πr^2h = 1/3πr^2h
πr^2 cancels out on both the left hand side and right hand side of the equation. It becomes
h = h/3
It means that the height of the cone is 3 times the height of the cylinder. Therefore,
If height of cylinder = 4 cm, height of cone = 12 cm
Answer:
Step-by-step explanation: okay each hour she makes 120 cookies right then 2 hours would be 240 and three hours would be 360 and 4 would be 480 and 5 would be 600 hundred
15 km = 5 trips
3km = 1 trip
24 km = 8 trips
