Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres
Given that t<span>he expression
represents the total length across the front of the mansion. Let the length of side I be a, then
</span>
) Using formula for cicumference.
Circumference = Pi * diameter
Circumference = Pi * 80m
Circumference = 251.2m.
Total inside length of the curved ends.
2)Total distance round inside of track =
2(125) + 251.2m
= 250 + 251.2
= 501.2m
3) Area of circular ends =
Pi*r^2
= Pi*40^2
= 5024m^2
Area of central area (rectangle)
length * width
125m * 80m
= 10,000m^2
Total area inside track =
5,024m^2 + 10,000m^2
= 15,024m^2
Hope this helps.

Answer:
The answer is "12 inches".
Step-by-step explanation:
Please find the image file of the graph.
We know 
so because the triangle is isosceles.
when 
is called by 
.
We know that 
since E and D are tangent points to a circle.
They have 
since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:
Therefore the length of
