Answer:

Step-by-step explanation:
The area of a circle varies directly as the square of its radius.

If r₁ = 2in, A₁ = 12.568 in₂, r₂ = 6.4 in, A₂ = ?
ATQ,

So, the new area of the circle is
.
1. 8.04
2. 122.86
These are the answers :D
The sum in sigma notation for the sequence will be as follows:
From
<span>5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)</span>∑(5(n-1)+5)
