Answer:
4,4
Step-by-step explanation:
Original Circle Area = 45
A = pi * r^2
Plug in what we know:
45 = 3.14 * r^2
Divide 3.14 to both sides:
14.3312102 = r^2
Find the square root of both sides:
r = 3.78565849
Find 2/3 of this:
2/3 * 3.78565849 = 2.52377233
So this is the radius of the newly dilated circle.
A = pi * r^2
A = 3.14 * 2.52377233^2
A = 3.14 * 6.36942677
A = 20
So the area of the newly dilated circle is 20 square inches.
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2x = 8 ( divide both sides by 2 )
x = 4
<h2>The length of each side of the equilateral traingle is 1/24 unit.</h2>
<u>Step-by-step explanation:</u>
Given that the perimeter of an equilateral triangle is 1/8 unit. With this information, we are asked to find the length of each side of yhe equilateral traingle.
The perimeter of equilateral traingle is defined as the three times of the length of edge. Mathematically;
→ Perimeter = 3a
By substituting the given values in the formula, we get the following results:
→ 1/8 = 3a
→ a = 1/24
Hence, the length of each side of the equilateral traingle is 1/24 unit.
<u>Additional information:</u>
- A triangle has three sides or edges.
- A triangle has three angles.
- A triangle has three vertices or corners.
- The sum of all internal angles of a triangle is always equal to 180 degrees. This is known as the angle sum property of a triangle.
- The sum of the length of any two sides of a triangle is greater than the length of the third side.
- There are three types of triangle, Scalene Triangle, Isosceles Triangle, Equilateral Triangle.
- Area of triangle = 1/2 * b * h.
- Perimeter of triangle = sum of all sides.
