Hi there!
The formula for the area of a circle is A = pi x r^2. Using this formula, we can plug in the radius and solve for the area.
WORK:
A = pi x (5)^2
A = pi x 25
A = 25pi cm^2
ANSWER:
B - 25pi cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
9.750
Step-by-step explanation:
formula for average rate of change is ;
f(b)- f(a)/b- a
here a = 1 and b = 2.5
f(b) = (2.5)^3 + 2 = 17.625
f(a) = 1^3+ 2 = 3
using the formula above, we have it that
(17.625-3)/2.5-1 = 9.750

In order to do this problem you must use square roots. Basically the same number multiplied twice to get your answer. In this problem, 5 * 5 = 25.
<h3>
18) 10m</h3>
Since they are asking for the square root to the nearest whole unit, we must know that the √105 lies in between 10 and 11, since 10 * 10 = 100 and 11 * 11 = 121. 105 is closer to 100 than it is to 121 and therefore the answer is 10.
