Are rectangle or garden has a length of 10.25 feet and a width of 6.2 feet. Another rectangle or garden has a length of 20.5 fee
Alinara [238K]
Hello!

The formula for finding area of a rectangle is length × width

<em><u>1st garden
</u></em>l = 10.25
<u><em /></u><em />w = 6.2

6.2 × 10.25 = 63.55

Area = 63.55 ft²

<em><u>2nd garden</u></em>

l = 20.5
w = 12.4

20.5 × 12.4 = 254.2

Area = 254.2 ft²

Divide the bigger area by the smaller area

254.2 ÷ 63.55 = 4

\framebox {4 times greater}

What's the circumference of a circle that is 9cm? Please explain step by step of how you got the answer...
Sauron [17]

Formula for finding circumference of a circle is 2πr.

Step-by-step explanation:

  • The given question says what is the circumference of a circle that is 9cm.
  • As radius is required for finding circumference of a circle, the formula is 2πr.
  • Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
  • If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
  • So the circumference of the given circle would be 18π or 56.52 cms.
