Answer:
6cm
Step-by-step explanation:
to find the diameter of a circle whose circumference is = 18 .84
the formula for finding the circumference of a crcle = πd
18.84 = πd
note π = 22/7 or 3.14
so,
18. 84 = 3.14 × d
divide both sides by 3.14
18.84/3.14 = 3.14d/3.14
6cm = d
therefore the diameter of the circle whose circumference is 18.84 is equal to 6cm
Answer:
a^3 + b^3
Step-by-step explanation:
(a + b)(a^2-ab+b^2)
a(a^2 -ab +b^2) +b(a^2-ab+b^2)
a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3
a^3 -a^2b +a^2b ab^2-ab^2 + b^3
The final answer will then be:
a^3 + b^3
Hope this helps! Have a great one! And I give out the best of luck for whatever quiz this is on!
Look at the left side of the polygon. Since they are both real numbers, we can use those to set up a proportion:
16:12=(x-1):6
Now, we can cross multiply and solve:
96=12(x-1)
96=12x-12
108=12x
9=x
The value of x is 9
Hope this helped!
