Answer:

Circumference = 56.52 \cm\\\\Area = 254.34 \ cm^2

Step-by-step explanation:

Taking π = 3.14

Circumference = 2 \pi r= 2 \pi \times 9 = 18 \pi = 18 \times 3.14 = 56.52 \ cm\\\\Area = \pi r^2 = \pi 9^2 = 81 \pi  = 81 \times 3.14 =  254.34 \ cm^2

Find the 4th term if the sequend in which a1 = 2 and a n+1 = -4a n + 2
pshichka [43]
a_n_+_1=-4a_n_+_2

dividing both sides by -4, we get:

a_n_+_2=- \frac{a_n_+_1}{4}

this means, each term is its previous term divided by -4.

now we can construct the sequence as follows:

a_1=2

a_2=- \frac{a_1}{4}= - \frac{2}{4}= -\frac{1}{2}

a_3=- \frac{a_2}{4} =- \frac{ \frac{1}{2} }{4}=- \frac{1}{8}

a_4=- \frac{a_3}{4}=- \frac{ \frac{1}{8} }{4}=- \frac{1}{32}



Answer: the last term is -1/32

Answer:

C = 37.6991

Step-by-step explanation:

The equation for the circumference of a circle is given: C = π · d

where, d is the diameter of the circle.

Plug in the value of d = 12 and use the π button on the calculator.

C = π · 12

C = 37.6991
