Answer:
Since the area of your base is 15, we multiply 15 by 10 since 10 is the height and 15 is the area of the base to get 150, now we divide by 3 since we are multiplying 150 x 1/3 = 50.
Formula of triangular pyramid:
1/3 x BH
In this case 15 is your base and 10 is your height
15 x 10 x 1/3(basically just dividing by 3) = 50
Answer: 30
Step-by-step explanation:
Because you can break the pentagonal base into triangles and the formula to find the area of a triangle is 1/2 Bh so 840/14 = 60 divided by 1/2 = 30
Answer:
The diameter of the circle is 8 inches
Step-by-step explanation:
The diameter is 2 times the radius
Ok to start you need to break this into a net in your head. Next, calculate each triangle
(6*7)/2 = 21
Then, multiply each triangle by the amount of them.
21*4 = 84
Next, get the area of the square.
7*7 = 49
Lastly, add the triangles and the square up.
49 + 84 = 133
