Answer:
<u>the first friend</u>
Explanation:
It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>
Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>
Therefore, we can make the conclusion that the first friend's response is correct.
<em>r = 15 cm</em>
<em>formula</em>
<em>V = πr²×h/3</em>
<em>replace</em>
<em>4950 = 22/7×r²×21/3</em>
<em>4950 = 22/7×r²×7</em>
<em>4950 = 22×r²</em>
<em>r² = 4950/22</em>
<em>r² = 225</em>
<em>r = √225</em>
<em>r = √15²</em>
<em>r = 15 cm</em>
I would refuse. if you dont refuse they can get probable cause
