Answer:
360 cm^2
Step-by-step explanation:
Find the area of each face of the triangular prism.
Imagine the triangular prism as its net, it is composed with 2 triangular faces (these are tye bases of the prism) and 3 rectangular faces.
Areas of the 2 triangular bases (they are similar triangles):
1/2 x 8 cm x 6 cm = 24 cm^2
24 x 2 = 48 cm^2
Area of the rectangular face:
8 x 13 = 104 cm^2
Area of another rectangular face:
6 cm x 13 cm = 78 cm^2
Area of another rectangular face:
13 cm x 10 cm = 130 cm^2
Add up all the areas of all faces:
48 + 104 + 78 + 130 = 360
So the SA is 360 cm^2
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)
The answer is B 113.04
Explanation
Assuming pi in this instance is 3.14
The formula for the area of a circle is A=(pi)r^2
Plug in the radius
A=3.14x6^2
Is 113.04
Answer:
The answer to your question is Volume = 32 u³
Step-by-step explanation:
Data
The volume of a rectangular prism = ?
Area of the base = 24
height = 4
Process
1.- Write the formula to calculate the volume of a pyramid
Volume = 1/3 Area of the base x height
2.- Substitution
Volume = 1/3 (24)(4)
3.- Simplification
Volume = 96/3
4.- Result
Volume = 32 u³
Answer:
5 is the answer. hope this help you
