In the attachement, there is what I came up with so far. I think that finding 'a' is non-trivial, if possible at all.
- the area of a circle
- the area of a circular segment
Answer:
112 m^2
Step-by-step explanation:
A = b * h
b = 9 + 5 = 14 m
h = 8 m
So
A = 14 x 8 = 112 m^2
Answer:
9.5 feet/ 1 second is your unit rate
Step-by-step explanation:
In order to make a unit rate you have to make the denominator 1 so it can be a whole number which means you divide by the denominator on both sides both numerator and denominator.
Answer:
Arc length is 12436.8m
Step-by-step explanation:
arc length =
* πD
where M is the angle measure of the arc
and D is the diameter
considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees
* π * 7917.5 = 12436.8m
Ratio is the comparison of sizes of two quantities of the same unit. Proportions are the equality of two ratios. A/b =c/d
