Answer:
If the prism is trapezoid then you need to find the height and use this formula
1/2 x a+b x h
This has been done below you only need to fill in the height and do the shape for 3cm x 2cm as you haven't been clear in your question.
Volume = 8 x h x 10 = 80 x h cm^3
Hope this helps.
Step-by-step explanation:
Slope triangle prism and or rectangle
The area can be seen either by finding height of the triangle or working out the rectangle and halving the rectangle.
Step-by-step explanation:
Volume
6 x 8 = 48cm^2
48 x 5 = 230cm^2 for double (rectangle prism of 6 x8)
385/2 = 115cm^2 triangle slope prism
---------------
Area first
trapezoid front measures 6,5, 10
1/2 x 6 + 5 x h
=1/2 x 6 + 5 x h
= 8 x h x 10= 80 x h
Volume = 8 x h x 10 = 80 x h cm^3
Answer:
B. Square
Step-by-step explanation:
Finding the side lengths :
<u>Side 1</u>
⇒ d₁ = √(-4 - 0)² + (8 - 8)²
⇒ d₁ = √16
⇒ d₁ = 4
=============================================================
<u>Side 2</u>
⇒ d₂ = √(-4 + 4)² + (8 - 4)²
⇒ d₂ = √16
⇒ d₂ = 4
===========================================================
<u>Side 3</u>
⇒ d₃ = √(-4 - 0)² + (4 - 4)²
⇒ d₃ = √16
⇒ d₃ = 4
============================================================
<u>Side 4</u>
⇒ d₄ = √(0 - 0)² + (8 - 4)²
⇒ d₄ = √16
⇒ d₄ = 4
As all sides of the figure are equal, and it creates 4 right angles, it is a square.

Answer:
25π/4 square meters
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius of the circle.
The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...
A = π(5/2 m)² = (25/4)π m²
The area of the circle is 25π/4 square meters.
__
As a decimal, that is 6.25π square meters.
Answer:
Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
Now we know x is 71
