Answer:
18.84 estimated, 6π exactly
Step-by-step explanation:
Hi!
<u>The formula for finding the circumference of a circle is 2πr:</u>
In that case, all we need to do <em>first </em>is to divide the diameter by 2, so we can substitute that into the equation.
6 ÷ 2 = 3
So we have 2π × 3 to solve.
2π × 3 = 6π
We can estimate the circumference by multiplying by 3.14.
6 × 3.14 = 18.84
(actually multiplying by π gives 18.849... which is pretty close!)
Thus, the circumference is
.
Hope this helps!
Answer:
c=-2
Step-by-step explanation:
Equation: -7c+2=16
-7c=16-2
-7c=14
c=14/-7
c=-2
Answer:
The answer is 10.5 or 10 1/2
Step-by-step explanation:
1) A=LxW
2) the height is given but you do not have the width So Divide.
3) first turn the fraction into decimals
H= 12 1/4= 12.25
A= 128 5/8= 128.625
4) 128.625 divided by 12.25 Give you 10.5
5) you can change 10.5 into a fraction 10 1/2
hopes this helps.
