Step-by-step explanation:
To find mean, average, divide.
-96/12
-8
U could use Photomath for that
Is it exterior as in on a line?? because 150 in a 360 angle is too small because 3601 -150 = 210 and that's too big for a triangle as it exceeds the rule of all angles in triangles add up to 180
Answer:
So we have a triangle and a semicircle.
If the triangle is equilateral, this is:
AB = BC = 6cm
Then the area of the triangle is equal to (base*height)/2
in this case:
A = (6*6)/2 = 36/2 = 18cm^2.
And the diameter of the semicircle is equal to 6cm, then the diameter is 3cm
And if the area of a circle is A = pi*r^2
then the area of half a circle is:
A = (pi/2*)3^2 = pi*4.5cm^2
Then, the area of the triangle plus the area of the semicircle is:
Total area = 18cm^2 + pi*4.5^2
