Answer:
The answer to your question is Circumference = 20π cm; Area = 100π cm
Step-by-step explanation:
Data
diameter = 20 cm
Circumference = ?
Area = ?
Process
1.- Write the formula of Circumference
Circumference = πd
-Substitution
Circumference = 20π
2.- Write the formula of area of a circle
Area of a circle = πr²
-Calculate the radius
radius = diameter/2
radius = 20/2
= 10 cm
-Substitution
Area = (10)²π
-Result
Area = 100π

Answer: The space given up by the students is 1/4 of the total space.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em> Students must give up half of the exhibit space to the other school.</em> So, we have to divide 5/10 by 2.
5/10 ÷ 2/1 = (5x1 ) / (10 x2 ) = 5 /20
Simplified (by 5) = 1 /4
The space given up by the students is 1/4 of the total space.

Answer:
true
Step-by-step explanation:
All you need to do is to subtract the x-coord. of G from the x-coord of H:
-2 - 3 = -5. Distance is not a signed quantity, so we'll give the final distance between points G and H as 5.
