What is the perimeter of a square which has the same area as a circle with circumference of 4π?
enot [183]

Answer:

perimeter = 8\sqrt{\pi }

Step-by-step explanation:

We require to calculate the area (A) of the circle

A = πr² ← r is the radius

circumference = 4π = 2πr, hence

2πr = 4π ( divide both sides by 2π )

r = 2, hence

A = π × 4 = 4π

The area of the square is therefore 4π and area = s² ← s is the side length

s² = 4π ( take the square root of both sides )

s = \sqrt{4\pi } = 2\sqrt{\pi }, hence

perimeter = 4 × 2\sqrt{\pi } = 8\sqrt{\pi }

What are the intercepts of -4x+6y-5z=60
AURORKA [14]
Equation is <span>-4x+6y-5z=60
x-intercept is obtained by assuming y=0, z=0, and solving for x.
-4x+0-0=60 => x=-15, hence x-intercept is (-15,0,0)
Similarly for y-intercept, assume x=0,z=0 =>
0+6y-0=60 => y=60/6=10 => y-intercept is (0,10,0)
Again, for the z-intercept, assume x=0,y=0 =>
0+0-5z=60 => z=-12 => z-intercept is (0,0,-12)</span>

Help me pleasee , timed
solong [7]

Answer:

The second alternative is correct

Step-by-step explanation:

We have been given the expression;

(x^{27}y)^{\frac{1}{3}}

The above expression can be re-written as;

(x^{27})^{\frac{1}{3}}*y^{\frac{1}{3}}\\\\(x^{27})^{\frac{1}{3}}=x^{27*\frac{1}{3}}=x^{9}

On the other hand;

y^{\frac{1}{3}}=\sqrt[3]{y}

Therefore, we have;

x^{9}\sqrt[3]{y}

Solve the linear expression 5(-3.4k-7)+(3k+21)
Ksivusya [100]

Our expression is below

5(-3.4k-7)+(3k+21) = 0

by solving it for the value of k

(-17k-35)+(3k+21) = 0

-17k+3k-35+21 = 0

-14k-14 = 0

-14k = 14

k = \frac{14}{-14}

k = -1
