I need help PLEASE no one has answered my question yet!!!!!!!!!!!!!!!!!!!!!!!!!! I NEED NUMBER 2
1 answer:
2. First you need to know about the pythagorean theorem which is
a^2 + b^2 = c^2. Look at the first picture below for more reference.
Next you use the pythagorean theorem to find out the right triangle sides to then know the length and width of the rectangle.
a = 8
b = unknown
c = 10
Now use algebraic steps. 8^2 + b^2 = 10^2 --) 64 + b^2 = 100 --) b^2 = 36 --)
b = 6 .
Finally you know the length which is 8 + 8 = 16 and the width which is 6, so the area of the rectangle is 16 x 6 = 96. And to look apporpriate 96in.^2 .

Answer:
Step-by-step explanation:
Total Surface Area of cylinder = Lateral Surface Area + Area of both circle bases.
Lateral Surface Area = Circumference of Circle Height
Lateral Surface Area =
Area of one circle base:
Area of both circle bases:
Total Surface Area =
The area of a figure is the amount of space the figure occupies
The surface area of the figure is 34.8 square meters
<h3>How to determine the area of the shape</h3>From the question, we have:
- The dimensions of the congruent squares are 3 m by 3 m
- The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 * Area of square + Area of parallelogram
This gives
Evaluate the products
Evaluate the sum
Hence, the surface area of the figure is 34.8 square meters
