Answer:
Area = 14.5
Step-by-step explanation:
Let's label the given coordinates A, B, C;
Thus;
A = (2, 3)
B = (-1, 0)
C = (2, -4)
From the coordinate geometry formula, the formula for area of a triangle with 3 vertices is;
Area = [Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By)]/2
Area = [2(0 - (-4)) + (-1)(-4 - 3) + 2(3 - (-4))]/2
Area = 29/2
Area = 14.5
\left[y \right] = \left[ -5\right][y]=[−5] totally answer
Answer:
I believe there would be 15.
Step-by-step explanation:
well 12×3=36
5×3=15 so 15:36
Answer:

Step-by-step explanation:
-A hemisphere is equivalent to half of a sphere.
- The area of a sphere is given by the formula:

-Given that r=3.6m, the hemisphere's volume can be calculated as:

Hence, the hemisphere's volume is approximately
