Answer:

a_{4} = 250

Step-by-step explanation:

To obtain any term in the geometric sequence multiply the previous term by the common ratio r

here r = - 5 and a_{1} = - 2, hence

a_{2} = - 2 × - 5 = 10

a_{3} = 10 × - 5 = - 50

a_{4} = - 50 × - 5 = 250

A circle inside of a square. The circle touches all sides of the square. The base is 5 centimeters.
lina2011 [118]

Answer:

19.6 cm²

Step-by-step explanation:

If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.

The area of a circle is given by:

A= \pi \frac{d^2}{4}

In this problem, d = 5 cm, the area of the circle is:

A= 3.14 *\frac{5^2}{4} \\A=19.6\ cm^2

The approximate area of the circle is 19.6 cm².
