I hope this helps.
Have a awesome day. :)

i will answer you other if u rate me brainliest
Not so sure about the second one, but the first one is pretty simple:
The area of a circle = pi x radius^2
Since you need to find the area of the entire dvd, I'm assuming they mean if the hole in the center wasn't there, so add that to the diameter.
12+1.5 = 13.5
Half of the diameter is the radius, so half of 13.5 = 6.75
Now, multiply pi (3.14) by the radius, but have the radius squared. You'd write the equation like this:
3.14 x 6.75^2 (or on paper, the ^2 would be a small two diagonal from the 5)
Actual answer: 143.06625
You can round that to 143.
77 rice balls. You can do this problem in 2 ways set up a proportion and solve for x or get the amount of grams needed to make 1 rice ball (100100/11) 9100g per rice ball and then you divide what you have 700700 by 9100 to get 77.
The missing side:
X= 40.70626 = 40.71
