To isolate r, first divide both sides by pi. That will leave you with r^2=A/pi. Then square root both sides to completely isolate r.
r=<span>√A/pi</span>
Answer:
52.765
Step-by-step explanation:
Day 1: $2.70 is added to the value of the share.
$43.85 + $2.70 = $46.55
Day 2: $2.70 is added to the value of the share.
$46.55 + $2.70 = $49.25
Day 3: $1.10 is subtracted from the value of the share.
$49.25 - $1.10 = $48.15
Day 4: $1.10 is subtracted from the value of the share.
$48.15 - $1.10 = $47.05
Day 5: $4.45 is subtracted from the value of the share.
$47.05 - $4.45 = $42.60
After 5 days, the value is $42.60, which is choice B.
Hope this helps!
<u>The approximate area of the </u><u>hexagon</u><u> = </u><u>672 cm²</u>
What is hexagon ?
- In geometry, hexagon is a polygon with 6 sides.
- If the lengths of all the sides and the measurement of all the angles are equal, such hexagon is called a regular hexagon.
- In other words, sides of a regular hexagon are congruent.
apothem of the hexagon = 14 cm
perimeter of the hexagon = 96 cm
Area of the hexagon = [(3√3) / 2] a² ; where a is the measure of the side
hexagon has 6 sides.
Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a
There are 6 triangles in the hexagon .
Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2
A = 112 cm²
The approximate area of the hexagon = 112 cm² * 6 triangles = 672 cm²
