Glass 1 is a right circular cylinder and Glass 2 is a cone. The total volume of water in both the glasses is 100 centimeters cubed. Some given dimensions are:
Right Circular Cylinder:
diameter = 5, thus radius is half of that, radius = cm
height = we need to find
(Note: Formula for volume, V, is )
Cone:
diameter = 6, thus radius is half of that, radius = cm
height = 5.2 cm
(Note: Formula for volume, V, is )
Now adding the 2 volumes and equating to 100, and then solving for h will give us our answer (we will use π as 3.14). Let's do this.
pir^2+1/3pir^2h=100
(3.14)(2.5)^2h+1/3(3.14)(3)^2(5.2)=100
19.625h+48.984=100
19.625h=51.016
h=51.016/19.625=2.60 cm
Hence height of glass 1 is 2.60
2.63 cm
Answer:
7
Step-by-step explanation:
7x2=14
14+6=20
Take 45.36 *.08 to get the price of the sweater 45.36 *.08 =3.6288 so take 45.36-3.63= 41.73 and take 41.73 *.25 = 10.4325 take 41.73+10.43=52.16 is the original price of the sweater
Let's just choose "x" as our variable for the length of a side of the triangle.
Two sides of a triangle are equal in length and double the length of the shortest side.
A triangle has 3 sides. Make the smallest side x then the two equal sides that are double the smallest side are both equal to 2x
The perimeter of the triangle is 35 inches. Perimeter is the sum of all sides.
x + 2x + 2x = 35
5x = 35
x = 7
So the smallest side is 7, and the other two sides are 14.
