Find the area and the circumference of a circle with diameter 8 cm. Use the value 3.14 for π , and do not round your answers. Be
Illusion [34]

Answer:

Area= 50.24 squared cm.

Circumference= 25.12 cm.

Step-by-step explanation:

To find the area of a circle- A= 3.14*(4 cm squared). ( The 4 cm is your radius. Half of the diameter.) After you square your radius you get 16cm squared. You then go onto multiply the 16 cm squared by 3.14 to get 50.24 cm squared.

To find the circumference of a circle- C= 2*(3.14)*(4cm). (Again the 4cm is your radius. Half of the diameter.) After you multiply the 2 and 3.14 you get 6.28. You then multiply the 6.28 by 4 cm to get 25.12 cm.

A hotel staff would like to create a circular flower bed for the hotel’s entrance. The flower bed will be enclosed by a border.
kiruha [24]

In order to solve this equation, first we must find the area of the entire circle and then we must find the area that the people like to plant with flowers. So the angle formed between 2 rock paths is 180 degrees. I am hoping that this answer has satisfied your query about this specific question.

6.5 x 1/9 please help
hjlf

Answer:

13/18

Step-by-step explanation:

  • 6.5 · 1/9 = 6 5/10 · 1/9
  • 6 5/10 · 1/9 = 6 1/2 · 1/9
  • 6 1/2 · 1/9 = 13/2 · 1/9
  • 13/2 · 1/9 = 13/18

Therefore, 6.5 · 1/9 = 13/18.
