Circumference = (π) x (diameter)
Circumference = 8π
(π) x (diameter) = 8π
Diameter = 8
Radius = 4
Area = π x (Radius)²
Area = π x (4)²
Area = π x (16) = <u>50.27 units²</u> (rounded)
The number of calories in 1 burgers is 180
The calories in the soda is 280
If
is true, then
is false, which in turn means
is true.
If
is false, then
is true, and so
is false.
So, because
in both cases, the statement is a tautology (always true).
If you were to put this in a table, you would have one column each for
. In the first column (
) you can think of
as an independent variable that can only take two values, true and false. In the next column (
), you would negate the value in the previous column. And so on.
It should roughly look like this:
p ... ~p ... ~(~p)
T ... F ... T
F ... T ... F
Answer:
Step-by-step explanation:
-we apply the relationship of chords intersecting within a circle:
-when two chords intersect to form a vertex of an angle within a circle, the measure of the angle is equal to one-half the sum of the measures of the two arcs intercepted by the angle and its vertical angle:
Hence, the measure of ∠AFE is 55°
