Answer:
1759.52cm^3
Step-by-step explanation:
Given data
Cylinder E
h = 30 cm and
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*30
V= 3.142*16*30
V=1508.16 cm^3
Cylinder F
h=5 cm
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*5
V= 3.142*16*5
V=251.36 cm^3
Hence the total volume is
=251.36+1508.16
= 1759.52cm^3
Answer:
x= 6.5 cm
Step-by-step explanation:
When a tangent line touches the circle, it forms a right angle triangle at that point
Apply the Pythagorean relationship in this case
Given that the height is = 20.2 cm = b
The hypotenuse is = c= x+14.7 cm
General formulae is;
a² +b² =c²
x² + 20.2² =( x+ 14.7)²
x² + 408.04= x² +14.7x+14.7x+216.09
x² + 408.04= x² + 29.4 x +216.09.........................collect like terms
x²-x² + 408.04-216.09= 29.4x
191.95= 29.4x-------------------------------divide by 29.4 t0 get x
191.95/29.4 =x
x=6.5 cm
8.03 times 10^5 or
8.03e+05
Answer:
Step-by-step explanation:
mean : added up the values and divide the result by the number of the values
Mr Jones = (5 + 6.25 + 5.75 + 6.50 + 8)/5 = $6.30
Mrs Jones = (5.50 + 7 + 6.25 + 5.75 + 7.75)/5 = $6.45
The difference between the two mean is 15 cents or $0.15
Answer:
For the first question it is 2.
2 x 2 = 4
5 x 2 = 10
4 + 10 - 14 = 0
The second question is -2
-2 x -2 = 4
5 x -2 = -10
4 + -10 + 6 = 0
Hope this helps
