1/2, 6/12, 9,/18, and 15/30
to answer on cube root we need to use the prime factorisation.
which means using only prime number and dividing the number by suitable prime number.
after find prime factorisation we know that cube root is 3th power of number.
so if we have same three number we need to take it as one because it is a cube root .
for example![\sqrt[3]{5*5*5} =\sqrt[3]{5^3} =5.](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B5%2A5%2A5%7D%20%3D%5Csqrt%5B3%5D%7B5%5E3%7D%20%3D5.%20)
I have to do formative assignments too
Answer:
C = 22π; A = 121π
Step-by-step explanation:
The relevant formulas for circumference (C) and area (A) are ...
C = πd . . . . . d is the diameter
A = πr² . . . . where r = d/2
Filling in the given value for diameter, we have ...
C = 22π
A = π(22/2)² = 121π
