Answer:
Step-by-step explanation:
The area of a triangle is one-half times the base times the height. The height of both triangles is 4 (the height of the triangle on the left is "outside" of the triangle). So the area of the triangle on the left is
so the area is 12
The area of the triangle on the right is
so the area is 16.
Adding those 2 areas together gives you a total area of 28 in squared.
Answer:
a^2 + b^2 = c^2
Step-by-step explanation:
With a triangle that has a right angle (90°) and squares are drawn on each of the three sides, the biggest square has the exact same area as the other two smaller squares added together.
a^2 + b^2 = c^2
see the picture.
Answer:
DA = 25
Step-by-step explanation:
Given that,
→ ABC = ADC ==> (1)
→ BA = 25 ==> (2)
From the given (1) and (2),
→ BA = DA
→ BA = 25
→ [ DA = 25 ]
Hence, the answer is 25.
Triangles ABC And DEF are not similar triangles.
Area of a circle is directly proportional to the square of radius of the circle while the circumference is proportional to the radius of the circle. This means that if the radius of a circle is increased x times, then its area will be increased to x^2 times the original area, and the circumference will increase to x times the original circumference.
Thus when the radius is doubled, or in other words if radius mad 2 time the original radius, the area of circle will become 2^2 = 4 time the original area. The circumference will become 2 times the original circumference.
We can calculate exact area and circumference of a circle from its radius using the following equations:
Area of circle = (pi/4)*r^2
Circumference of circle = 2*pi*r
Where r is the radius of the circle.
I know this is a lot, sorry.
