Answer:

The circumference of circle is 15.7 feet

Step-by-step explanation:

First, you have to find the radius of circle by dividing the diameter by 2 :

radius = diameter \div 2

radius = 5 \div 2

radius = 2.5 \: feet

Next, you have to substitute it into the formula of circumference, C = 2×π×r where r represents radius :

C = 2 \times \pi \times 5

let \: \pi = 3.14 \\ let \: r = 2.5

C = 2 \times 3.14 \times 2.5

C = 15.7 \: feet

Please help!! Very urgent..thank you!!

Answer : 4 times

Here it's given that ,

  • The height and base of the butterfly sitting on the stem (red butterfly) is two times greater than the height and base of the butterfly sitting on the flower .

And we need to find out how many times the area of red winged butterfly is greater than that of sitting on the flower (blue butterfly) .

Let us take ,

  • base of blue butterfly be b
  • height of blue butterfly be h
  • Area be A .

Then ,

  • base of red butterfly will be 2b .
  • height of red butterfly will be 2h .
  • Area be A' .

We know that ,

→ area of the triangle = 1/2 × base × height

So that ,

→ A/A' = (1/2 * b * h) ÷ (1/2 *2b *2h)

→ A/A' = bh/4bh

→ A/A' = 1/4

→ A' = 4A

<u>Henceforth</u><u> the</u><u> area</u><u> of</u><u> </u><u>blue</u><u> butterfly</u><u> is</u><u> </u><u>4</u><u> </u><u>times </u><u>greater</u><u> than</u><u> </u><u>that</u><u> of</u><u> </u><u>red </u><u>winged</u><u> butterfly</u><u> </u><u>.</u>

I hope this helps.
