804.24 - we know this because the area of a circle is r^2*pi. If we double the radius we get (2r)^2*pi or 4r^2*pi. We notice that this is just 4 times the area of the original circle, equating to 804.24.
Answer:
80.7 inches
Step-by-step explanation:
circumference = 2 * pi * r
2 * pi * r = 507 inches
r = (507 inches)/(2 * pi)
r = (507 inches)/(2 * 3.14159)
r = (507 inches)/(6.2832)
r = 80.7 inches
Answer:
the second one -(1/4)^3
Step-by-step explanation:
-(1/4)^3
= -(1^3/4^3)
= -1/64
Step-by-step explanation:
Hey there!
Given;
4(X+1) -3 and 4x+1.
No, they are equivalent.
<u>Reason: </u>
Solving 1st expression.
4(x+1) = 4x + 4 - 3
Now, next expression is: 4x+1.
So, 4x + 4 = 4x+1
So, they are equivalent to eachother.
