The problem did not state if the 1cm measure is the radius or diameter.
Area of a circle = π r²
Assuming: 1 cm is the radius
Area of 1 button = 3.14 * (1cm)² = 3.14cm²
Total area = 3.14cm² * 7 buttons = 21.98 cm²
Assuming: 1cm is the diameter : radius is 1/2 = 0.50cm
Area of 1 button = 3.14 * (1/2cm)² = 3.14 * 0.25cm² = 0.785cm²
Total area = 0.785cm² * 7 buttons = 5.495cm²
This is a whole squared equation. So, it is (x+2)^2.
If you check it, you get x2 + 4x + 4
Hope this helps!
Answer:
D I think
Step-by-step explanation:
I'm not 100% sure
Area of a square =a^2
40000=a^2
a=200 inch
Now if u can imagine a square shape with side of 200 inch each.it makes right angles
so use pythagorean theorm
c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch
ength of a fence is 282.84 inch
Answer: (8,10)
Step-by-step explanation:
To go from A to C, we go right 2 units and up 6 units.
So, if we let the fourth vertex be D, then to go from B to D, we must also go right 2 units and up 6 units from B.
Therefore, the answer is (8, 10).
