Answer:

1244.3 square units

Step-by-step explanation:

The area of a composite figure can be found by decomposing it into its parts, then adding the areas of those parts. This figure can be decomposed into a square of side length 22 units, and two circles, each with radius 11 units.

<h3>Square</h3>

The area of a square is the square of its side length.

A = s²

A = 22² = 484 . . . . square units

<h3>Circles</h3>

The area of a circle is given by the formula ...

A = πr²

A = π(11²) = 121π

The area of the two circles is twice this value, or ...

2A = 2(121π) = 242π ≈ 760.3 . . . . square units

<h3>Total</h3>

The area of the figure is the sum of the areas of its parts:

total area = square area + area of circles

total area = 484 +760.3 = 1244.3 . . . . square units

Rewrite the expression using positive exponents<br> 1. 1/9x^-2y^-1<br><br> 2. a^-5*a^-8

NikAS [45]

Answer:

Property : a^-b = 1/a^b

Using this property, we can rewrite the expression using positive exponents :

$1. \frac{1}{9}*x^{-2} *y^{-1} =\frac{1}{9}\frac{1}{x^{2} } \frac{1}{y} =\frac{1}{9x^{2} y} \\2. a^{-5} a^{-8} =\frac{1}{a^{5}a^{8} } =\frac{1}{a^{13} }$
