Mathematics
1 answer:
djyliett [7]3 years ago
6 0

Answer:

Exact circumference is 7\frac{49}{150}km

Approximate circumference is 7.33 km

Step-by-step explanation:

We are given;

  • The diameter of a circle as 2\frac{1}{3} km

We are required to determine the exact and approximate circumference of the circle.

  • We know that the circumference of the circle is given by;
  • Circumference = πD, where D is the diameter

Taking π as 3.14

Circumference=3.14 (2\frac{1}{3}km)

                          =7\frac{49}{150}km

The exact circumference of the circle is 7\frac{49}{150}km

7\frac{49}{150}km=7.327 km\\                            = 7.33 km (nearest hundredth)

Thus, the approximate circumference of the circle is 7.33 km

2p^2 -1 =7 <br> Would appreciate some help thank you
SIZIF [17.4K]

Answer: p = 2

Step-by-step explanation:

To solve this problem, you first have to add 1 to each side of the equation, leaving you with 2p^2 = 8. Then you divide by 2 on both sides leaving you with p^2 = 4. After that, you take the square root of both sides, and because 4 is a perfect square, you get p = 2 as your final answer.

A student solved for the radius of a circle with a circumference of 12π
padilas [110]

Answer:

Step 4 is incorrect  he did not divide correctly from step3 to step 4

Step-by-step explanation:

The circumference of a circle is

C = 2 * pi *r

We know the circumference is 12 pi

12pi = 2 pi *r

Divide each side by 2 pi

12 pi/2pi = 2pi r/ 2pi

6 = r

From step 3 The student did not cancel the pi in the top and the bottom on the right hand side to isolate r

In step 4 he got 6 =pi r  instead of pi

Carla gets a 96% on a 50 question test . What what fraction of the answers did she get wrong?
LenKa [72]
Hello!

To find this out, figure out the amount of questions she got correct..

To get that number, multiply 96% as a decimal, (0.96) by 50.

0.96 * 50 = 48.

Turn 48 into fraction, (over 50)

48/50 is the answer.

Hope this helps!
