Answer:
Your answer is 64pi square inches
Step-by-step explanation:
The diameter is 16 so the radius is 8.
So the area is pi(r^2)= pi(8^2)
=64pi square inches
Answer:
8x + 40y
Step-by-step explanation:
<u>Step 1: Distribute</u>
4(2x + 10y)
(4 * 2x) + (4 * 10y)
(8x) + (40y)
<em>8x + 40y</em>
<em />
Answer: 8x + 40y
Let
C---------> the circumference of a circle
D---------> diameter of a circle
r----------> radius of a circle
we know that
C=2*pi*r
D=2*r
so
C=D*pi-------------> pi=C/D
<span>Pi is defined as the ratio of the circumference of a circle to the diameter of that Circle
when you multiply the diameter in both numerator and denominator
pi*D=(C/D)*D------> pi*D=C
and the diameter is two times the radius
so
D=2*r
C=pi*D------> C=pi*(2*r)-----> C=2*pi*r
therefore
the answer is the option D
</span>Two times r equals the diameter of the circle. Pi equals the circumference divided by the diameter. When you multiply, the diameter is in both the numerator and the denominator, which cancels out, leaving the circumference
Answer:
Step-by-step explanation:
nth root of a number 'a' is represented by the expression,
In this expression 'n' = Index of of the radical
is called the 4th root of 16.
In , the index is 4 and the radicand is 16.
4th root of 16 can be represented by
= 2
