Answer:
200.96
Step-by-step explanation:
A = πr²
A = 3.14 x 8²
A = 3.14 x 64
A = 200.96
X =
-3 or -4 or -5 or -6 or -7 and to -infinity
A= π r ²
Take half of the diameter for the radius, so the radius is 2m
A=π 2 ²
A= 12.57 m²
So, yes, you are correct
Answer:
5
or 18.03
Step-by-step explanation:
Let's call the unknown leg x
Using the Pythagoras rule
19^2 = 6^2 + x^2
361 = 36 + x^2
subtract 36 from both sides
361 - 36 = x^2
325 = x^2
Take the square root of both sides
= 
= x
x = 5 = 18.03
To find the missing value of the equation 3-X=11 first move all the terms that have X to the right side of the equation. So -X=8( Since 11-3=8). Then divide both sides of the equation by -1 to get rid of the negative on the X. Your answer is X=-8.
