Answer: The correct options are
(B) (x-6)^2+y^2=36,
(D) (x+6)^2+y^2=36.
Answer:
Solution given;
angle =270°
radius [r]=8cm
we have
length of arc =270°/360°×2×π*r
=270°/360°×2×3.14*8=37.68cm
<u>length of the </u><u>arc</u><u> </u><u>is</u><u> </u><u>37.68</u><u>cm</u><u>.</u>
Answer:The length is 13/2, while the width is 15/4, after combination. Ratio of length to width is then (13/2)/(15/4) = 26/15.
B
Any point reflected across the x axis is (x,-y) so (2,3) becomes (2,-3)
