Answer:
c=2(3.14)r
given c=14(3.14), then r
make r the subject formula and substitute given c=14(3.14)
r=c/2(3.14)
r=14(3.14)/2(3.14)
r=7
Step-by-step explanation:
Ok so to solve to first one u do this:
62.4 - 31.53, which gives u 30.87. and then u add 30.87 and 31.33, and u get 62.4
for the second one u do the same thing.
12ab will be the right answer.
Since 24a^3 = 12ab(2a^2)
And 36ab^2 = 12ab(3b)
Subtract 1:
x/4=2
multiply by 4:
x=8 which is the answer
