What is the approximate circumstance of the swimming pool? Use 3.14 as an estimate for pi. ○- 3.5 m =radius

The answer would be -21.98

Step-by-step explanation:

Circumference is found by multiplying radius times 2 times pi.

Which would be -3.5(2)(3.14) and you would get -21.98.

Hope I helped!! :)

Sorry if it's wrong! :(

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
