Answer:3/4
Step-by-step explanation:
Multiply 1/6 by 2 to get 2/12 and then add that to 7/12 and get 9/12
If you simplify that you end up with 3/4
20 and 40 don't belong, 1x1 is 1,2x2 is 4, and you would keep going and when you hit 5, 5x5 is 25 and 7x7 is 49 not 40
Technically speaking, yes, but the size would be different for some
SA = surface area of the sphere
SA = 4*pi*r^2
200 = 4*pi*r^2
200 = 4*3.14*r^2
200 = 12.56*r^2
12.56*r^2 = 200
r^2 = 200/12.56
r^2 = 15.9235668789809
r = sqrt(15.9235668789809)
r = 3.99043442233811
The radius is r = 3.99043442233811
so the diameter is
d = 2*r
d = 2*3.99043442233811
d = 7.98086884467621
Answer: 7.98086884467621
Round this however you need to
