Answer:
112 in^2
Step-by-step explanation:
The equation to calculate the area of a circle is A=πr^2. We can solve for the radius of the circle by:
1) plugging in our known value, A=7. So 7=πr^2
2) dividing both sides by π.
7/π=r^2
3) square rooting both sides.
Sqrt(7/π)=r
Plug that into a calculator and you get about 1.4927
Now we multiply that by 4, giving us our new radius of about 5.9708
Plugging that number back into the equation A=πr^2 as r will give us 112.
Answer:
I -3/20
Step-by-step explanation:
-3 2
---- * -----
8 5
Multiply the numerators
-3*2 = -6
Multiply the denominators
8*5= 40
The fraction is
-6/40
Both the top and the bottom can be divided by 2
-6/2 = -3
40/2 =20
The fraction becomes
-3/20
Answer:
19.47m
Step-by-step explanation:
Radians = π/180 * degree
0.0174 x 124 = 2.164 rad
Arc AB = Radius * Angle ( In Radians )
AB = 9 x 2.164
=> 19.47m
