Can anyone help me please?

Step-by-step explanation:

diameter:4in

π≈3

redious

area of the circle

to figure out the area

we need to figure out the redious first

so the redious is 4/2 =2in

and the area of the circle is

πr²

3×2² in²

3×4 in²

12 in²

the answer is 5/14.

hope this .

(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
