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:
Group A has greater variability in the data.
Step-by-step explanation:
We use elimination. Clearly, from the MAD, Group A has greater variability in the data.
So, choice 1.
1 lb ≈ 0.454 kg
1 in ≈ 2.54 cm
I'm not sure I understand the "do not" part of this question. What does it mean to convert from cubic inches (volume) to inches (length), and from centimeter to cubic centimeters?
In any case, you have
(1 lb)/(32.375 in³) ≈ (1 lb)/(3.19 in)³
… ≈ (1 lb)/(3.19 in)³ × (0.454 kg)/(1 lb) × ((1 in)/(2.54 cm))³
… ≈ (0.454 kg)/(3.19 in)³ × ((1 in)/(2.54 cm))³
… ≈ (0.454 kg) × ((1 in)/((3.19 in) × (2.54 cm))³
… ≈ (0.454 kg) × (1/(8.10 cm))³
… ≈ (0.454 kg) × 1/(530.531 cm³)
… ≈ (0.454 kg)/(530.531 cm³)
… ≈ 0.000856 kg/cm³

Answer:
(-13, -12)
Step-by-step explanation:
The midpoint (x,y) between two points (
) and (
) on the coordinate plane is given by:
Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be (). Hence:
Therefore house C is at (-13, -12)
