Answer:
452.39 mm^2
Step-by-step explanation:
Area of a circle = 
r^2
Here r = 12mm
Therefore, Area= x 12^2 = 452.389342...
Round to required degree of accuracy = 452.39mm^2
Hope this helps
I believe you can do x + 2.7 = 16.
I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.
Your answer is 16 - 2.7
(13.3)
Answer:
Step-by-step explanation:
y = f(x)
y = 2x+3
You need to switch the places of x and y, into this:
x = 2y + 3
Then solve for y:
2y = x-3
Area of triangles:
0.5x9=4.5
4.5x2=9 (i divided 4 (the amount of triangles) by 2 instead of dividing 4.5 by 2)
area of square:
0.5x0.5=0.25
surface area of whole thing:
9+0.25=9.25
so the answer is 9.25
hope this helps :)
