1/2 area of circle (16pi)/2 . plus (length of the botton 15 by pythag. times 8 divided by 2 )===== .
8pi plus 127.5
Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
The final answer is choice C) cos(x)Have a look at the attached image to see my work on how I got that answer.
Ten times ten equals one hundred, if that's what you are asking for.
