Hey!
So you have a net of the figure. It's broken into several 2D shapes. What you an do it find the area of each shape and add it together.
Triangles:
A = (b*h)/2
A= (5 * 3) / 2
A = 15/2
same thing for the second one
15/2 * 2 = 15
Don't forget, there are 2 triangles so it's really 15 for both
Rectangles:
A=b*h
A= 7*5
A=35
A=7*5
A=35
A=3*7
A=21
35+35+21=91
Now add the sum of the area of the triangles and the sum of the area of the rectangles
91+15 = 106
106 is the surface area
Hope this helps!
Answer:
do you have a picture of this
Answer: 10pi
Step-by-step explanation:
C=2*pi*r
C=2*pi*5
C=10*pi (exact)
This is exact if u want numbers, you’ll have to round-off and you can just put 10xpi into a calculator If u want to see.
