What is the value of a3 in the sequence? a3 the 3 is squared below of a

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 $a_3 = \frac{-1}{2}$

<BAC = <DEC = 30°

<BCA = <DCE = 70°

<CDE (or m<D) = 180° - <DEC - <DCE

<CDE = 180° - 30° - 70°

<CDE = 80°

The number that belongs in the green box is 80

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: $100*254.3=25430 in^{2}$
