The circumference of the circle is 37.68 ft
Step-by-step explanation:
Given,
The area of the circle is 113.1 sq ft
To find the circumference of the circle we need to find the radius of the circle first
Formula
The area of circle with radius r is = π
sq unit
The circumference of circle with radius r is = 2πr unit
Let us take the radius of the circle is r ft
According to the problem,
π
or, 
or, 
or, r = 
or, r = 6
Now,
The circumference of the circle is 2×3.14×6 ft = 37.68 ft
Answer:
yes it is arithmetic because:
28 - 10= 18
18 - 10= 8
8 - 10= -2
it keeps decreasing by the same number (10). Therefore, it is arithmetic.
Answer:
28 questions answered.
Step-by-step explanation:
40(2/5) is 16 questions.
40-16 is 24 questions left.
24(.5) is 12 questions.
16+12 gets you 28 questions.
Answer:
y = 45x miles
Step-by-step explanation:
Speed is the rate of change of distance with time. Mathematically,
speed = distance/time
Given that Darla travels at a constant speed of 45 miles per hour and for y miles, it takes her x hours then
45 = y/x
multiply both sides by x
45x = y
then the number of miles (y) Darla can drive in x hours
y = 45x (in miles)
C: 12/35a^3
2 multiplied by 6 is 12.
5 multiplied by 7 is 35.
a^1+a^2=a^3.
