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
Answer:
All of the above
Step-by-step explanation:
In Pythagorean Theorem, a and b are the short and long leg, and c is the hypotenuse.
I’m pretty sure the answer is 3 because the z stands for a missing number so 2+3=5

Answer:
T(0, –3)
Step-by-step explanation:
triangle ABC was translated down 3 points, so if you subtract 3 from each of ABC's points, you'll get triangle A'B'C'
