Answer:
Area of bigger circle = 36.32cm²
Step-by-step explanation:
Kindly find attached rough sketch for your reference
This problem bothers on the mensuration of flat shapes, a circle

Given data
Area of small circle =9cm³
Say we assume the all unit is in cm
From the diagram we can see that the diameter of the small circle is the radius of the bigger circle
So let us solve for the diameter of the small circle
9= πr²
r²=9/3.142
r²= 2.86
r=√2.86
r= 1.7cm
But diameter of small circle
d= 2r
d= 1.7*2= 3.4cm
Hence the radius of the bigger circle is 3.4cm
Area of bigger circle =πr²
=3.142*3.4²
=3.142*11.56
Area of bigger circle = 36.32cm²
-6 = r cos α and -8 = r sin α
r = sqrt( 6^2 + 8^2) = sqrt 100 = 10
α = arctan ( -8/-6) = arctan (4/3) = 53.13 degrees
polar firm = r ( cos α + i sin α)
= 10(cos 53.18 + i sin 53.18)
its been a long time but ui think thats correct

Answer:
Do you want to know the surface area of the triangle or the perimeter of the triangle?
Step-by-step explanation:
If you are looking for the Surface area, plug your numbers in this formula: SA=(p x h)/(2) + B where SA is the surface area of the pyramid, p is the perimeter of the base, h is the slant height of the pyramid, and B is the area of the base.
