Answer:
8 inch
Step-by-step explanation:
dilation actor = 4/5
Scale dilation is used to change the dimensions of the line segment or anuy measurement in length.
So, 10 inch segment = 
inch
thus, the 10 inch segment is equal to 8 inch on the scale.
By definition the perimeter of an ellipse is given by:
Where,
a: semimajor axis of the ellipse
b: minor semiaxis of the ellipse
Substituting values we have:
When doing the corresponding calculations, we have that the perimeter is given by:
Round to the nearest tenth:
Answer:
the estimated perimeter of the ellipse is:
If by "long leg lengths" you mean the hypotenuse then the area is 116 sq. units. If you mean the bases of the triangles then the area is 170 sq. units.
If the length of 12 is the hypotenuse, we first must find the base of the triangles using the Pythagorean theorem:
10² + b² = 12²
100 + b² = 144
b² = 44
b = √44 = 6.6
This means we have two triangles and a rectangle. The area of the rectangle is 5(10) = 50 sq. units. The area of each triangle is 1/2(6.6)(10) = 33. Adding all 3 together we have:
50+33+33 = 116 sq. units.
If the 12 is the base, then we have the rectangle with the area of 5(10) = 50 and two triangles each with an area of 1/2(12)(10) = 60:
50+60+60 = 170 sq. units.
Answer:
12.56 m
Step-by-step explanation:
If the radius is 2, the the diameter will be 4 since the diameter = 2 radius. Next, you will multiply 3.14 * 4 to get your answer:
12.56 m
