The result would be 72... 12
x6
----
72 (carry the one) Unless your figuring out if its positive or negative. (positive)

Circumference = πD
------------------------------------------------------------------------
Given that the circumference is 75cm, find Diameter:
------------------------------------------------------------------------
πD = 75
D = 75 ÷ 3.14
D = 23,89 cm
------------------------------------
Find Radius:
------------------------------------
Radius = Diameter ÷ 2
Radius = 23.89 ÷ 2
Radius = 11.94 cm
------------------------------------
Find Surface Area:
------------------------------------
Area = πr²
Area = 3.14 x 11.94²
Area = 447.65 cm²
------------------------------------
Answer: 447.65cm²
------------------------------------
For this case we have the following vector:
v = (- 2, -1).
Using product point we have:
v.v = (-2, -1). (- 2, -1)
v ^ 2 = (-2) * (- 2) + (-1) * (- 1)
v ^ 2 = 4 + 1
v ^ 2 = 5
Then, clearing the module we have:
v = root (5)
Answer:
The module of the vector is given by:
v = root (5)
C. square root of 5
