3.14159265359
Step-by-step explanation:
Most people just use 3.14 for math though
Surface area is the area of the faces added together.
First lets find the area of one of the triangles.
Area of triangle is 1/2*base*hight
Area=1/2*2*3= 3
Area of ONE tringle is 3, and area of the FOUR tringles is 4*3 whihc is 12
Now lets find area of square
area of square is side*side
So, area is 2*2 which is 4
Now lets add area of triangles+area of square
12+4 which 16
Surface area is 16
You can plug in values into the equation to see which one makes it true
x=3
7+18=16+9
25=25
C. 3
Answer:
3(5 +6) = <em>33</em>
Step-by-step explanation:
3(5+6)
so first you multiply 3 by 5
which is 15
then you multiply 3 by 6
which is 18
and that remains as 15+18
which in total equals <em>33</em>
