Answer:
Part A : About 5,931
Part B : 5,930.8
Part C : Yes, because it rounded it to the nearest full number
Answer:

Step-by-step explanation:
Given:
The area 'A' of a circle with radius equal to 'r' is given as:

In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.
Dividing both sides by π, we get:

As
, the above equation becomes:

Taking square root both the sides, we get:

We neglect the negative result while taking square root as the radius can't be a negative number.
Thus, the formula for radius 'r' in terms of area 'A' is given as:

Its D. -18 hope this helps :D
44 = 11
---- ----
p 5
Cross multiply
44*5 = 11p
You end up with ;
220 = 11p
Divide 220 by 11 to get p by itself
20 = p <-- that's your answer
hope i helped :)
Answer:
putting value of m and n in the equation we get
10x5+ 4x2
= 50+8=58
