The answer is yes. here is how:
circumference of a circle is 2pi*r
perimeter of a square is 4a, a being the length of each side.
when 2pi*r=4a, r=(2a)/pi
area of the circle is pi*r^2=pi(2a/pi)^2=(4/pi)*a^2
area of the square is a^2
Because 4/pi is bigger than 1, (4/pi)*a^2 is always larger than a^2
Question 1:
The labeled points are points from the drawing are:
A,B,C,D,E
Question 2:
The intersection of the two lines is a point since the necessary condition for the two lines to intersect is that they should be on the same plane, hence they form a point.
Thus the correct answer is: True
Question 3:
The name for a given line is given from the end points that forms the line. Hence given that the two points forming the line is B and P, the correct answer is option C]
Question 4:
There are 5 letters and you use 2 to name the line, so the number of choices will be given by:
5C2=5!/(2!(5-2)!)
=(5×4×3×2×1)/(2×1×3×2×1)
=10
Question 5:
Collinear points are three or more points which lie on the same single straight line. In our case the points are:
T,X,V
Answer:
G
Step-by-step explanation:
Answer:
339π in³
Step-by-step explanation:
The amount of water is the difference between the volume of the cylinder and the volume of the ball. The appropriate volume formulas are ...
cylinder V = πr²h
sphere V = (4/3)πr³
For the given numbers, the volumes are ...
cylinder V = π(5 in)²(15 in) = 375π in³
sphere V = (4/3)π(3 in)³ = 36π in³
The water volume is the difference of these ...
water volume = cylinder V - sphere V
= 375π in³ - 36π in³ = 339π in³
