Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
Answer:
C. Up.
Step-by-step explanation:
We have been given that the parent function
is transformed to the function
. We are asked to describe the given transformation.
Let us recall the transformation rules.
,
,
,
.
Upon comparing our transformed function with the parent function, we can see that the graph is shifted to left by 7 units and upwards by 5 units.
Therefore the correct choice is option C.
Irrational numbers are numbers that have decimals and the decimals randomly keep going on. Remember, a repeating decimal is not necessarily an irrational number. (pi, sqrt(2), etc)
An integer is a whole number. (1, 2, 3, 4, etc) it could also be negative.
Answer:
A
Step-by-step explanation:
The points seem to be clustered around a curve.
225 * 2 = 450
If the elephant drinks 225 liters of water a day it would wrong 450 liters of water in 2 days because 225 * 2 = 450
