Answer:
34.9^2
Step-by-step explanation:
Well if one side is 4 cm then the square is 16cm^2.
The area of a circle is pi r^2.
So the radius is 2.
we plug 2 in.
pi 4
12.6/2
6.3
6.3 * 3 = 18.9cm^2
18.9 + 16 = 34.9
Ok then after that what’s the question ?
Answer: You basically have to 2xlw+2wh+2lh which means
2 multiplied by the length and width + 2 x the width and the height+ 2 x the length and height
Example:
l= 2
w=5
h=4
2x2x5+2x5x4+2x2x4
I hope this helps
Answer:
80
Step-by-step explanation:
28-28=0
0-12= -12
28+12 = 40
28-40 = -12
40 is the increase
40 is half of 80
So, the answer is 80
To check: -12 + 40 (half of a number; 80) = 28
