Answer:
A=pi times radius squared
24/2= 12 is the radius (since it's half of diameter)
A=pi times 12 squared
12 squared is 12 times 12 which is 144
A=pi times 144
A=452.389342
Rounded to 452.4
2x6 + 4x5 + x4 + 11x3 + 2x2 + 4x + 4
Step-by-step explanation:
C≈43.98cm
C=2πr
d=2r
C=πd=π·14≈43.9823cm
A linear pair are two given angles whose sum is equal to .
Let the exterior angle be represented by , and the three interior angles of the triangle be represented by , and .
Assume that the vertex angle is the linear pair to the exterior angle .
i.e + = (sum of angles on a straight line)
Thus,
i. + = (sum of two opposite interior angles is equal to an exterior angle)
⇒ = -
Also,
= -
But,
+ + = (sum of angles in a triangle)
⇒ = - ( + )
and
+ = -
ii. + + = (sum of angles in a triangle)
= - ( + )
+ =
$104
$260 - 60% = $104
