<em>B) exactly one solution</em>
Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 7.13² × 
= 
≈ 22.2 ft² ( nearest tenth )
Well, the square root of 82 is an irrational number, so
it can never be completely written with digits. As a
decimal, it goes on and on forever, and never ends.
As a fraction, it can't be written at all.
The square root of 82 is approximately 9.055 .
(That number is about 0.0043% too small, which is pretty close.)
Answer:
Her cousin used Yard to measure the wall.
Step-by-step explanation:
Firdaus measured the length of the wall and got 9 feet.
Her cousin measured the same distance and said that it was 3.
To find the answer, we have to use division.
Let "x" the divisor which divide 9 and gives the answer 3.
9 ÷ x = 3
3x = 9
To find x (divisor) we need to divide both sides by 3, we get
3x ÷ 3 = 9 ÷ 3
x = 3
So 1 unit cousin's measure = 3 feet Firdaus measure
We know that 1 yard = 3 feet.
Therefore, her cousin used Yard measure to measure the wall.
Answer:
3.67 units
Step-by-step explanation:
The central angle is at the point (0,0).
Then it's at the point (1,0)
Then it moved 210 degrees.
Let's bear in mind that we start moving the degree from it's current position.
So moving 210 degrees is moving 180 degrees plus 30 degrees.
Moving 180 degrees I like transforming linearly.
Now the location is at (-1,0)
But the distance covered will be
= 2πr*210/360
r = 1
= 2*3.142*1*(210/360)
= 6.144*0.5833333
= 3.67 units
