Answer:
153.86
Step-by-step explanation:
formula - A = π × r2
3.14 x 7^2
= 153.86
The area of a circle if the diameter is 80 is
A=5026.55
Given,
Nepali speaker : 80% (Y)
Maithili speaker : 60% (X)
We know that,
Both language speaker = Y -X
Now,
Y- X
= 80- 60
= 20
Therefore, 20% people speak both languages
Answer:
The answer is
, or the first option.
The last option isn't correct for this answer, even though it is correct mathematically. This is because it wants the fully simplified version, so the 5o squared would turn into a 5 and a 2, with the 5 multiplying the -6, and the 2 remaining underneath the square root.

To solve the problem, substitute the given points for x in the given equation to get

Solving the three equations simultaneously, we have:
a = -3, b = 2 and c = -5
Therefore, the required equation is
