i think
A=π(10t)2=100πt2
B.
A=100×3.14×32=2826
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent
When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
460 (envelopes) / 30 (minutes) = 15.3 rounds down to 15 envelopes per minute
