The complete question in the attached figure
Part a)
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6√2 cm
sin 45=AB/AC-----> AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm
the answer part a) is
AB=6 cm
Part b)
we know that
volume of the pyramid=(1/3)*Area of the base*height
area of the base=50 cm²
height=6 cm
so
volume of the pyramid=(1/3)*50*6----> 100 cm³
the answer part b) is
100 cm³

Answer:
Hence r=10.3 cms (rounded to tenth place)
Step-by-step explanation:
In Triangle KLN ,
KN = 5 Cms
LN = ½ of LM
As the Perpendicular dropped from the center to the chord bisects it.
LM = 18 cm
LN = 9 cm
Now we have to find r or KL
We apply Hypotenuse Formula in this
The formula is given as
Where c = r
a=5
b=9
Putting them in the formula
