Find the area of a circle with a circumference of 6.28 units. _______units^2

Mathematics
1 answer:
hichkok12 [17]3 years ago
6 0

Answer:

Area of the circle= 3.14units^2

Step-by-step explanation:

Circumference of the circle=6.28 units

Finding the radius:

Circumference of a circle =2*\pi *r

6.28=2*\pi *r\\

As, \pi =\frac{22}{7}=3.14

So,    

           6.28=2*3.14*r

          6.28=6.28*r

Dividing by '6.28' both side:

        r=6.28/6.28

           r=1unit

Area of the circle= \pi *r*r

                      =3.14*1*1\\\\=3.14*1\\\\=3.14units^2

Area of the circle= 3.14units^2

I think of a number and add one fourth of it to half of it and the result is twelve. What is the number I thought of?
belka [17]

Suppose that the number u were thinking about is x thus :

\frac{1}{4} x +  \frac{1}{2} x = 12 \\

Multiply both sides by 4

4 \times ( \frac{1}{4} x +  \frac{1}{2} x) = 4 \times 12 \\

x + 2x = 48

3x = 48

Divide both sides by 3

\frac{3x}{3}  =  \frac{48}{3  }  \\

x = 16

Yuki888 [10]

Answer:

about 3 1/2 hours long

Step-by-step explanation:

70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.
