kkurt [141]

Answer:

Option D is correct.

a_3 = \frac{-1}{2}

Step-by-step explanation:

The sequence is in the form of :

a_1, a_2, a_3, a_4, .......

where

a_1 represents the First term.

a_2 represents the Second term.

a_3 represents the Third term.

a_4 represents the Fourth term and so on.....

we have to calculate the a_3 in the given sequence:

Given the sequence:  -4 , -2, -\frac{1}{2} , -\frac{1}{4}, ......    

a_3 = \frac{-1}{2}

Therefore, the third term a_3 = \frac{-1}{2}

The circumference of a standard bowling ball is about 27 in. To the nearest unit, how many square inches is the surface area of
Sidana [21]
The surface area of a sphere is S=4 \pi  r^{2} where r is the radius;
The circumference is 2 \pi r=27 in so that r= \frac{27}{2 \pi }=4.5 in using this value we can evaluate the surface area of 1 ball as:
S=4 \pi r^{2} =4 \pi  (4.5)^{2} =254.3  in^{2}
For 100 ball you get: 100*254.3=25430  in^{2}
