Radius(R)=10cm
We know,
Area of circle(A)=πr^2
=3.14×10^2
=3.14×100
=314cm^2

An environmental agency studying the effects of drought on a lake found that the water level decreased at a constant rate during the first few months of the drought. When the agency began its research, the depth of the lake was 346 feet. The table represents the agency’s susequent observations about the lake's depth.
Which equation represents the depth of the lake, y, based on the number of weeks passed, x?
y = -0.6x + 346
y = -1.2x + 346
y = -0.6x
y = -1.2x
The value of 15% of 12 meters is 1.8 meters.
A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred. The word "per 100" means "per percent." The number "%" is used to symbolize it.
Given to find 15% of 12 meters
15% is written as
15/100
and 15% of 12 is, multiply it by 12
12 x 15/100
180/100
= 1.8 meters
Hence the value is 1.8 meters.

How many corners are in a rectangle and how many flat faces
Answer:
Number of People in the basketball game =A four digit number having 3 in the tens place.
Total number of digits in all={0,1,2,3,4,5,6,7,8,9}=10
So, Required Number,that is number of people at the basketball game which is a four digit number,also digits can repeat
=(0 can't be at Unit place ,so first digit that is number at thousands place can be selected in 9 ways)(Number at Hundred place can be selected in 10 ways )(3 in tens place)( Number at Unit place can be selected in 10 ways )
=9939(Maximum People)
Total number of four digit numbers , if these condition are given
=9×10×1×10
=900
