10
Step-by-step explanation:
11+9=20
20/2
You need a height measurement in order to find the area.
For the first part, a is the answer because we want km over mi and for the second part, multiply 1km/0.62mi times 23km which equals 14.26 miles
Answer: 254.35ins
Step-by-step explanation:
Circumference of a circle = 2πr or πd.
Given the area of the circle = 56.52ins. To find the area of the circle, we first need to find the radius of the circle first by making r the subject of the formula.
2πr = 56. 52
r = 56.52
----------
2π
where π = 3.14
Now put this in r above and solve
r = 56.52/2 x 3.14
= 56.52/6.28
= 9ins.
Now to find the area of the circle substitute for r in the equation of the area of the circle below
Area of circle = πr²
= 3.14 x 9²
= 3.14 x 81
= 254.35ins
Answer:
Step-by-step explanation:
Factor out a 6 from the numerator and 2 from the denominator
2 in the denominator divides the 6 in the numerator
factor the denominator, let me know if you need help with this
the (x+6)s cancel
