Answer:
251.2 m
Step-by-step explanation:
Circumference = 2 x π x r
C = 2 x 3.14 x 40
C = 251.2
ANSWER
b=11
EXPLANATION
The given quadratic equation is
We expand to get:
We simplify further by combining the x terms.
This is the standard form.
Comparing to
We have b=11
Let p positive number:
p²+44²>250250
p²>250250-44²
p²>248314
take the square root of both sides:
√p²>+√248314
p> 498.3 or 500 is the number
Note that A of a circle is A = pi*r^2.
Here, we use A = 3.14*r^2.
We are able to solve this for r^2: r^2 = A / 3.14
If A = 1964 square units, then r^2 = (1964 sq units) / 3.14, or about 625 sq units, so that r is about 25 units. This would be the largest possible radius.
f A = 1810 square units, then r^2 = (1810 sq units) / 3.14, or about 576 sq units, so that r is about 24 units. This would be the smallest possible radius.
The radius would be between 24 and 25 units long (answer)
24 is the answer you are looking for
