Diameter of a circle = 28 m

Then, radius of the circle will be :

= \tt \frac{diameter}{2}

=\tt  \frac{28}{2}

= \tt14 \: m

Thus, the radius of this circle = 14 m

Area of circle :

= \tt\pi  {} {r}^{2}

=\tt 3.14 \times 14 \times 14

= \tt3.14 \times 196

= \tt615.44 \:  {m}^{2}

Thus, the area of this circle = 615.44 m²

Circumference of circle :

= \tt2\pi r

=\tt 2 \times 3.14 \times 14

= \tt87.92 \: m

The circumference of this circle = 87.92 m

Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m

bonufazy [111]

Answer: the answer is -6

2(n+5) = -2

2n + 10 = -2

2n = -2 - 10

2n = -12

2n *1/2 = -12 * 1/2 = -6

n = -6

Which are the solutions of x^2 = –11x + 4?
strojnjashka [21]

This is a quadratic equation, i.e. an equation involving a polynomial of degree 2. To solve them, you must rearrange them first, so that all terms are on the same side, so we get

x^2 + 11x - 4 = 0

i.e. now we're looking for the roots of the polynomial. To find them, we can use the following formula:

x_{1,2} = \frac{-b\pm\sqrt{b^2-4ac}}{2}

where x_{1,2} is a compact way to indicate both solutions x_1 and x_2, while a,b,c are the coefficients of the quadratic equation, i.e. we consider the polynomial ax^2+bx+c.

So, in your case, we have a=1,\ \ b=11,\ \ c=-4

Plug those values into the formula to get

x_{1,2} = \frac{-11\pm\sqrt{121+16}}{2} = \frac{-11\pm\sqrt{137}}{2}

So, the two solutions are

x_1 = \frac{-11+\sqrt{137}}{2}

x_2 = \frac{-11-\sqrt{137}}{2}
