If the area of a circle is 31.36pi, then what is its radius?

1 answer:

4 0

You would:

31.36 divided by pi and that will give you r2
you would then need to divide r2 by 2 to get the radius and there is your answer
I got:
9.982 for the first part
then 9.982 divided by 2= 4.991 for my final answer
I hope this helps

Find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.

Tatiana [17]

Solution:

we have been asked to find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.

Here we can see

m appears 1 time.

i appears 4 times.

S appears 4 times.

p appears 2 times.

Total number of letters are 11.

we will divide the permutation of total number of letters by the permutation of the number of each kind of letters.

The number of distinguishable permutations $=\frac{11!}{1!2!4!4!} \\$

Hence the number of distinguishable permutations $=\frac{11!}{1!2!4!4!}=34650 \\$

Answer:

x = 14°

Step-by-step explanation:

here we can see ( 6x + 5 ) is parallel to 89°, has same angle.

6x + 5 = 89 .............. as they are similar

6x = 89° - 5°

6x = 84°

x = 84 / 6

x = 14°
