I got it its this answer i used mathpapa for this
Well, first you have to convert to one unit... then simplify
D:H
150m:16500cm
150m:160m
150:160
30:33
10:11
Answer:
Circumference of circle = πd = π × 16 =16 π in.
or
circumference of circle = 2πr = 2×π×8= 16 π in.
6(7+5) + 3
Hope this helps :)
To check:
PEMDAS
7+5 is 12
6(12) + 3
72 + 3
75
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
