The area of a circle is calculated as pi*(r^2). Given a diameter of 26 cm, the radius is half the diameter, which is 26/2 = 13 cm.
Therefore the area is pi*(13^2) = 169 pi.
Another alternative formula for the area is pi*(d^2 / 4). Substituting d = 26 would give pi*(26^2 / 4) = pi*(676/4) = 169 pi, which is the same answer.
So the correct answer is C.
The average will be the third number, because the first and fifth, as well as the second and fourth, will average out to the third.
The answer is compound inequality
Answer:
2a^2b(5a-3b)
If not then the other way is
5a-3b
Step-by-step explanation:
The GCF of 10a^3b and -6a^2b^2 is 2a^2b
So divide by that you will get
2a^2b(5a-3b)
The expression is: a. StartFraction (3) sine (66 degrees) Over sine (38 degrees) EndFraction
Step-by-step explanation:
The Law of Sines is written as;

where a, b,c are sides of the triangle and side a faces angle A , side b faces angle B and side c faces angle C.
In this case,
Dividing side AB by sin 38° equals dividing side BC by sin 66°

3/0.61566147532 = BC/0.91354545764
4.87280773645 = BC/0.91354545764
BC=4.87280773645*0.91354545764 =4.45153137359
Approximate length is = 4.5 and the expression is: 3 sine 66°/ sine 38°
