÷
3×2×1
Cancel same numbers in the numerator and denominator.
So you're going to have= 9×8×7×6×5×4 divided by 1
Which gives you, 60,480.
Hope this helped:) Mark me brainiest please.
Answer:
C = 22π; A = 121π.
Step-by-step explanation:
To find the circumference of a circle, you do pi times the diameter. That would be 22pi.
To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.
So, C = 22pi; A = 121pi.
Hope this helps!
