Answer:
84
Step-by-step explanation:
Using the definition
n ! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then = 9/6 3 = 987654321/654321321
Cancel 6(5)(4)(3)(2)(1) on numerator/ denominator, leaving
= 987/321
=504/6
= 84 → B
The radius of circle C is also 3 times greater than the radius of circle D.
The area of circle C:
A C = (3r)² π = 9 r² π
The area of circle D:
A D = r² π
9 r² π : r ² π = 9
Answer: It is 9 times the area of circle D.
