.......
-7 -1 = -8
-3 -4 -5 -6 -7 -8
Answer:
A=330
Step-by-step explanation:
im not sure which is the length width height
but if length is 10
width is 3/5
height is 15
A=2(wl+hl+hw)=2·(0.6·10+15·10+15·0.6)=330
then the area would be 330
The anwser to your question is 1 and 5/7
An arc of length 30 m : l = 30 m.
r = 15 m, ∠ A = ?
Formula for the length of an arc is:
l = r π A / 180° ( where A is the central angle )
A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 °
This is very close to your result.
