Lets get started :)

The circumference formula of a circle is
C = 2 $\pi$ r (r being the radius)

If radius = 45, substitute 45 instead of r

C = 2 $\pi$ (45)
=90 $\pi$
≈ 282.7433388

I suppose you leave it in the pi ( $\pi$ ) form

Answer:

(x - 3)² + (y - 3)² = 4

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, 3) and r = 2, thus

(x - 3)² + (y - 3)² = 4

( t^15/27x^9 ) ^-2/3 Please solve this it is fraction with a negative fraction exponent

Answer:

Step-by-step explanation:

Exponent laws:

$(a^{m})^{n}=a^{m*n}\\\\a^{-m}=\frac{1}{a^{m}}$

$(t^{\frac{15}{27}}x^{9}})^{\frac{-2}{3}}= \ t^{\frac{15}{27}*\frac{-2}{3}}*x^{9*\frac{-2}{3}}\\\\\\= t^{\frac{5}{9}*\frac{-2}{3}}*x^{3*-2}\\\\=t^{\frac{-10}{27}}x^{-6}\\\\=\frac{1}{t^{\frac{10}{27}}x^{6}}$
