Find the circumference of the circle with 1/4 Pi square centimetre square 2​

Mathematics

otez555 [7]3 years ago
4 0

Answer:

The circumference of the circle is 6 cm (approximately).

Step-by-step explanation:

Given:

Area of the circle = 1/4π²

Now, to get the circumference of the circle we need the radius.

So, finding the radius by putting the formula of area:

Area = \pi r^{2}

\frac{1}{4} \pi ^{2} = \pi r^{2}

dividing π by both sides:

\frac{1}{4}\pi=r^{2}

using square root on both the sides:

\frac{1}{2}\sqrt{\pi } = r

So, the radius is \frac{1}{2}\sqrt{\pi }

Now, putting the formula of circumference:

circumference=2\pi r

                              =2\pi\frac{1}{2} \sqrt{\pi}

                              =\pi \sqrt{\pi}

putting the value of π =3.14

                              =3.14\times\sqrt{3.14}

                              =3.14\times1.77

                              =5.56

Circumference = 5.56 cm

Therefore, the circumference of the circle is 6 cm (approximately).

Point A(3,2) is on a circle whose center is C(−2,3). What is the radius of the circle?
goldfiish [28.3K]

Answer:

The radius of the circle is √26.

Step-by-step explanation:

Since point A is on the circle, the distance between that point and the center of the circle is equal to the radius.

To find the distance between two points, the following equation should be used:

x^{2} =(x_{A}- x_{C}) ^{2} + (y_{A}- y_{C}) ^{2}

Replacing the numeric values:

r^{2} =(3- (-2)) ^{2} + (2-3) ^{2}\\r^{2} =(5) ^{2} + (-1) ^{2}\\r=\sqrt{26}

The radius of the circle is √26.

Rico walked for 3/10 mile. Then he walked for 24/100 mile. How far did he walk in all?
grigory [225]
First, Rico walked for 3/10 of a mile which is 30/100 of a mile.
Hen, Rico walked for 24/100 of a mile.
Then you add 24/100 and 30/100. 24+30/100 which is 54/100.
Answer=54/100 of a mile

Answer:

x2 =  -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600
