Answer:
Area = πr²
Circumference = 2πr
Step-by-step explanation:
When given the radius r ,
Area of a circle A = πr²
Circumference of the circle C = 2πr
When given diameter d,
Area of a circle A = πd²/4
Circumference of a circle = πd
To find the radius r and d from area A,
r = sqrt(A/π)
d = sqrt(4A/π)
To find the radius r and diameter d from a given circumference C,
r = C/(2π)
d = C/π
Where d = 2r
To find the volume of a cylinder, start with the formula for the volume of a cylinder.
Volume =
Notice that our cylinder has a radius of 7 and a height of 16. So we have
() (7) (16)
Let's start by simplifying the exponents. ≈ 49
() (49) (16)
49 × 16 = 784
We can add a unit so we have 784.
