Answer:
160.14 mm^2
Step-by-step explanation:
Area of a circle = pi r^2
subtract the area of the smaller circle from the larger
note that the smaller radius = 7 mm
pi ( 10^2 - 7^2 ) =
3.14 ( 51) = 160.14 mm^2
Answer:
19
Step-by-step explanation:
When 2 chords intersect then the product of the parts of one chord equal the product of the parts of the other chord, that is
12(x - 7) = 4(x + 3) ← distribute parenthesis on both sides
12x - 84 = 4x + 12 ( subtract 4x from both sides )_
8x - 84 = 12 ( add 84 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
12 + x - 7 = 12 + 12 - 7 = 17
4 + x + 3 = 4 + 12 + 3 = 19 ← longer chord
Answer:
0
Step-by-step explanation:
(y2-y1)/(x2-x1)= slope
(4-4)/(4-(-6)) = 0
Answer: ok it is 81/100.
Step-by-step explanation:Just add them together which gives you 81/100 .chnage 7/100 to 70/100 then combine 11/100 which equals 81/100.
