I take it you meant above to be a multiplication, so then,
<span><span><span>(−∞,0)</span>∪<span>(0,∞)</span></span><span><span>(-∞,0)</span>∪<span>(0,∞)</span></span></span><span>{x|x≠0<span>}</span></span>
Answer:
Answer:
Radius of the circular garden
= 210 sq
=105m
Radius of the region covering the garden and the path =105m+7m
=112m
Area of the region between two concentric circles
with radius of outer circle R, and inner circle r =π(R sq−r sq)
Hence, the area of the path
=π(112sq−105 sq)= 7/22
(12544−11025)
= 33418/7
=4774m sq
