Answer 1
Answer: the correct question is
a) A balloon has a circumference of 28 in. Use the circumference to approximate the volume of the balloon to the nearest cubic inch.

or

b) A balloon has a circumference of 28 in. Use the circumference to approximate the surface area of the balloon to the nearest square inch.

case a)
we know that
circumference=2*pi*r
clear variable r
r=circumference/(2*pi)
circumference=28 in
r=28/(2*pi)----> r=4.46 in

volume of a balloon=(4/3)*pi*r³-----> (4/3)*pi*4.46³----> 371.61 in³
Volume=372 in³

the answer is
372 in³


case b)
we know that
circumference=2*pi*r
clear variable r
r=circumference/(2*pi)
circumference=28 in
r=28/(2*pi)----> r=4.46 in

surface area of a balloon=4*pi*r²-----> 4*pi*4.46²---> 249.83 in²
Surface area=249.83 in²-------> 250 in²

the answer is
250 in²

1, ½, 0, ...; 16th term

Answers

Answer:

a₁₆ = - (13)/(2)

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

(1)/(2) - 1 = - (1)/(2)

0 - (1)/(2) = - (1)/(2)

this indicates the sequence is arithmetic with nth term formula

a_(n) = a₁ + d(n - 1)

where a₁ is the first term , d the common difference , n the term number

here a₁ = 1 , d = - (1)/(2) , n = 16 , then

a₁₆ = 1 + (- (1)/(2) × 15 ) = 1 + (- (15)/(2) ) = (2)/(2) - (15)/(2) = - (13)/(2)
