So if the formula is A=(pi)r^2, find the area of the entire circle:
A=(pi)(13^2)=530.66cm
then find the area of the little circle:
A=(pi)(3^2)= 28.26cm
then subtract the little circle from the big circle:
530.66cm-28.26cm= 502.4cm
and there you go. Hope this helps!
The difference (the answer of a subtraction problem) is:
2/7 - 2/5 --> 10/35 - 14/35 = -4/35
The answer sum (the answer of an addition problem) is:
2/7 + 2/5 --> 10/35 + 14/35 = 24/35
Hope this helps.
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
To determine how many he can burrow in 7 minutes, you would multiply the
unit rate of 3 holes in 1 minute by 7.
He would burrow 21 holes in 7 minutes.
