Answer:
<u>d = 2r or d = C/π</u>
Diameter is equal to two times the radius or Circumference/π
<u>C = 2πr</u>
Circumference is equal to two times π multiplied the radius
<u>A = π * r²</u>
The area of the circle equals to π multiplied by the radius squared
Step-by-step explanation:
Let's find the formulas for d, C and A
d = diameter
C = Circumference
A = Area
r = radius
π ≅ 3.1416
d = 2r or d = C/π
Diameter is equal to two times the radius or Circumference/π
C = 2πr
Circumference is equal to two times π multiplied the radius
A = π * r²
The area of the circle equals to π multiplied by the radius squared
Answer:
Mean: 14
Step-by-step explanation:
(44+63-17+28-30-24+19+51-8)/9 = 126/9
= 14
X=55 Explanation: the square is a right angle symbol and that means the angle is 90 degrees so just subtract 35 from the 90 to get x
Answer:
x = 2
Table:
0,0
3,9
-2,-6
4,12
Step-by-step explanation:
distribute
3(2x+1)=15
6x+3 = 15
subtract 3 from both sides
6x + 3 = 15
6x + 3 - 3 = 15 - 3
simplify
6x= 12
divide both sides by 6
answer= x=2
