Circumference=2 times pi times radius
if we use 22/7 as pi
2 times 22/7 times 14
multiply them
2 times 22/7=44/7
44/7 times 14=616/7=88
the circumfence=88 cm
7m - 3n
m = 3, n = 2
Replace m and n with the appropriate numbers:
7(3) - 3(2)
Multiply both sides:
21 - 6
Subtract:
21-6 = 15
Here's how one would solve it:
17 + 3x2 = 6x
17 + 6 = 6x
23 = 6x
x = 23/6
There's only one solution.
Answer:
a. 44
Step-by-step explanation:
using inverse cosine we can find the angle since we have the length of the hypotenuse and adacent
cos^-1 (13/18) = 43.76
