Answer:
Area of the circle with a radius of 12 meter is 1386
.
Step-by-step explanation:
Given :
Radius of a circle = 21 meter.
pi (π) = 22 over 7
To find :
Estimate the area of a circle.
Formula used :
Area of the circle = π ×
.
Explanation : We are given that
Radius of the circle = 21 meter.
pi (π) = ![\frac{22}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B7%7D)
Plugging the given values in above formula,
Area of the circle =
×
.
On simplification we get,
Area of the circle = 1386
.
Therefore, Area of the circle with a radius of 12 meter is 1386
.
21/25 is the highest score
Divide 21 by 25 and you will get .84
Which is 84%
<h2>
Answer: 55 degrees</h2>
Step-by-step explanation:
Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles
,
and
:
![\theta+\alpha+\beta=180\º](https://tex.z-dn.net/?f=%5Ctheta%2B%5Calpha%2B%5Cbeta%3D180%5C%C2%BA)
Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:
![XYZ+YXZ+XZY=180\º](https://tex.z-dn.net/?f=XYZ%2BYXZ%2BXZY%3D180%5C%C2%BA)
![50\º+75\º+XZY=180\º](https://tex.z-dn.net/?f=50%5C%C2%BA%2B75%5C%C2%BA%2BXZY%3D180%5C%C2%BA)
![XZY=180\º-50\º-75\º](https://tex.z-dn.net/?f=XZY%3D180%5C%C2%BA-50%5C%C2%BA-75%5C%C2%BA)
Finally:
![XZY=55\º](https://tex.z-dn.net/?f=XZY%3D55%5C%C2%BA)
Answer:
Two congruent figures
Step-by-step explanation:
Here we have to use the definition of congruent.
Congruent means equal to each other.
Example.
If the two triangles said be congruent, their corresponding angles and corresponding sides are equal.
They will have to same size of the sides and same measure of angles.
Two equal polygons, that is two congruent figures.
Hope this will help you.
Thank you.
