The perimeter of the shape is 94 cm and the area is 462 sq cm.
Step-by-step explanation:
Given,
The radius (r) = 14 cm
To find the area and perimeter of the given shape.
The given shape is of the full circle.
Formula
The perimeter of the circle = 2πr
The perimeter of the given shape = (2πr)+r+r =
(2πr)+2r
The area of the circle = πr²
Now,
The perimeter of the given shape = (2×
×14)+2×14 = 94 cm
The area of the given shape = (πr²)
= ×
×14² = 462 sq cm
For a better understanding of the solution/explanation given here please go through the diagram in the file attached.
By definition, an angle bisector is a ray that divides an angle into two congruent angles.
In our question we have been given that GJ is the ray that is the angle bisector and that has been shown in the diagram.
Now, since, , therefore, the ray
will divide the original angle
into two congruent angles,
and
. Since, the division is equal, the values of both these angles will be half of the original angle. Thus, we will have:
Thus, the required value of
