Question

pplease answer correctly​

Answer 1

Answer:

1) circumference of circle = πd

2) $p^{2}$ - $q^{2}$ = ( p + q) (p - q)

3) Surface area of cube = 6 * $Sides^{2}$

4) $(p - q)^{2}$ = $p^{2}$ - 2pq + $q^{2}$

Answer 2

Answer:

1. circumference — πD

2. p²-q² — p²-2pq+q²

3. Surface area of cube —6 × side²

you have write something wrong because the meaning of question '1' and '2' is same in match the fallowing..

if you solve p²-q² the answer is (p-q)²...

so , you have done something wrong in question ....
