Answer:
r=10.0
(10.0267614148)
Step-by-step explanation:
So circumference=2πr
63=2πr
lets divide both sides by π
20.0535228296=2r
lets divide both sides by 2, you should have your answer
r=10.0267614148, but since we are rounding to the nearest tenth it should be r=10.0
hope i could help :)
Answer:
Step-by-step explanation:
Now e have two figures
1 is ABCD and other is APQD ,
Now to find g and f,
Now the are both figure is ,
Area = length * width
Area ABCD = 39 cm^2
AB* BC = 39
Again,
Area APQD = AP*QD= 16 cm ^2
from here f =16/g putt it in above equation we get ,
(g+7)*16/g = 39
16*g-39*g+96 =0
-23g +96 = 0
g = 96/23
g =3 cm
Now for f putt in one of the above equation ,
f =16/3
f =5.33 cm
2x2 +3x -7 =x2 +5x +39
2x2 +3x -7 -x2 -5x -39=0
x2 - 2x -46 =0
(x-1)2 -46 -1 =0
(x-1)2 -47=0
(x-1)2 = 47
x-1= + or - the square root of 47
x= 1 + or - the square root of 47
Answer:
-14
Step-by-step explanation:
as usual u should do the equation that inside the brackets.
x+(6+8)
x+14
-14=x
