Answer:
For the answer to the question above, first you must find the area of the rectangle, which is 3 × 6 = 18 inches squared. Then, you find the area of the triangles. To find the area of the top triangle, you'd do base × height/2 (5 × 6)/2 = 15 inches squared. The triangle on the left would be (4 × 3)/2 which is 6 inches squared. After you've added up all of the values, you get (18 + 15 + 6) = 39 inches squared
Step-by-step explanation:
Answer:
If 21 is the height, and 4 is the radius, then the volume is approx. 1055.58
Step-by-step explanation:
Answer:31.6
Step-by-step explanation: i did the test
If you plot the triangle on a graph, you'll see that the shape is a right triangle. Using the distance formula we can calculate the distance between point A and point B, which is the hypotenuse.

5 + 6 + 8 = 19. The perimeter of triangle ABC is 19 units. Hope this helps:)
