i have a field 60m long and 110 wide going to be paved i ordered 660000000cm cubed of cement how thick must the cement be to co

Sveta_85 [38]

<span>First find the area of the field
A=WL
A=(110m)(60m)
A=6,600m^2
Now turn the cm into m
becouse 100cm^3=1m^3
660,000,000cm^3=6,600,000m^3
Now find out how many times you can cover the filled
6,600,000m^3/6,600m^2=100m
So it will be 100m thick.
P.S. I'm assuming you meant you jest forgot the m for 110m.</span>

What is the ratio of the circumferences for two circles with areas 6π m2 and 150π m2?

hichkok12 [17]

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{Area_1}{Area_2}\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{6 \pi }{150 \pi }\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{1 }{25}\bigg)
$

$\dfrac{Length_1}{Length_2} = \sqrt{ \dfrac{1}{25} } 
$

$\dfrac{Length_1}{Length_2} = \dfrac{1}{5}$

-------------------------------------------------------------
Answer: The ratio of the two circles = 1 :5
