The answer is 78.5 you can get this by multiplying pi by the radius which is 5 then square it and you get 78.5

Answer:

a=78.5 meters^2

Step-by-step explanation:

First, we have to find the radius

r=d/2

r=10/2

r=5

Substitute 5 in for r in the area formula

a= $\pi$ r^2

a= $\pi$ 5^2

a= $\pi$ 25

Substitute 3.14 in for pi

a=25*3.14

a=78.5 meters^2

Hope this helps!

namely, how many times does 4 x 10⁻³ go into 8 x 10⁶.

$\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\a^{-n} \implies \cfrac{1}{a^n}\qquad \qquad\cfrac{1}{a^n}\implies a^{-n}\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\-------------------------------\\\\\cfrac{\stackrel{elephant}{8\times 10^6}}{\stackrel{ant}{4\times 10^{-3}}}\implies \cfrac{8}{4}\times \cfrac{10^6}{10^{-3}}\implies 2\times 10^6\cdot 10^3\\\\\\2\times 10^{6+3}\implies 2.0\times 10^9$

In a 30-60-90 triangle the long leg is half the hypotenuse.

pentagon [3]

And because we know that we cut the base of the equilateral triangle in half, we can see that the side opposite the 30° angle (the shortest side) of each of our 30-60-90 triangles is exactly half the length of the hypotenuse.
