D = 10cm

10 divided by 2 = 5

Pi (3.14)

3.14 x 5^2

Answer:

78.5 cm^2.

Step-by-step explanation:

The diameter d = 10 so the radius = 1/2 * 10 = 5cm.

Therefore the area = π r^2

= π * 5^2

= 3.14 * 25

= 78.5 cm^2.

Evaluate (−23)×(−23)3 by using the Laws of Exponents
Nikolay [14]

Given:

\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3

To find:

The value of given expression by using the Laws of Exponents.

Solution:

We have,

\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3

Using the Laws of Exponents, we get

=\left(-\dfrac{2}{3}\right)^{1+3}      [\because a^ma^n=a^{m+n}]

=\left(\dfrac{-2}{3}\right)^{4}

=\dfrac{(-2)^4}{(3)^4}      [\because \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}]

=\dfrac{(-2)\times (-2)\times (-2)\times (-2)}{(3)\times (3)\times (3)\times (3)}

=\dfrac{16}{81}

Therefore, the value of given expression is \dfrac{16}{81}.
