61-27=34
:D this is really neat. Thanks!
Answer:
28.27
Step-by-step explanation:
Area of a circle A≈ πr2
3.14 x 3^2 ≈ 28.27
4/100= 0.04
0.04 x 250 = 10 (This is the interest earned in the year)
250+10 = 260
The diagonal AC, along with the base AB and length BC, forms a triangle. The triangle's dimensions are:
AC = 18
∠CAB = 20°
AB = ?
∠ABC = 130°
BC = ?
∠BCA = 180 - 20 - 130 = 30°
Thus, we may apply the sine rule:
sin(BCA) / AB = sin(ABC) / AC
AB = sin(30) * 18 / sin(130)
AB = 11.7 inches
It's wrong because 6x10 to the 3rd power is 6000, not 180.
