Answer: 18.86 feet
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = πD
Where D represents the diameter of the circle.
The circumference of the inner circle is 44 ft. It means that
22/7 × D = 44
22D = 7 × 44 = 308
D = 308/22
D = 14 ft
The distance between the inner circle and the outer circle is 3 ft. This means that the diameter of the outer circle would be
14 + 3 + 3 = 20 ft
Circumference of the outer circle is
22/7 × 20 = 62.86 ft
The number of feet by which the circumference of outer circle is greater than the circumference of the inner circle is
62.86 - 44 = 18.86 feet
B: Apply the distributive property to get 4x - 12=9
No. when the line reaches 4 on the x axis it is at 13 on the y axis.
C. The distance around the circle is the correct answer.
The formula is:
f ( x ) = a ( 1/2 )^x + 16
If it passes through the point: ( 1, 8 )
a ( 1/2 ) ^1 + 16 = 8
1/2 a = - 8
a = - 16
Answer:
f ( x ) = - 16 ( 1/2 )^x + 16
