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.
Answer:
Apples
Step-by-step explanation:
To find the cost per pound you need to divide the amount of money by the amount of apples: $6/5 which equals $1.2 or $1.20
If A,B and C lie on the same line:
4x- 9 + 3x+5 = 17
7x = 21
x = 3
Answer:
18
Step-by-step explanation:
When x equals -3, then the first equation is simplified to 9 + 6 + 3 = 18; and the second equation confirms the same answer by showing -6 x -3 = 18
751*5=3.755, which is the number of toys made in a week.
By multiplying 3.755 by 3, you find that the workers make 11.265 toys in three weeks.
