Since the tortoise was 56 years old 11 years ago, we add 11 to 56 to get its current age of 67 years old.
Answer:
V = 2458.10 cubic inches
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
π - 3.142
h - 19.1 inches
d - 12.8 inches
Calculate the radius
Diameter = 2 * radius
Radius = diameter/2
r = 12.8/2
= 6.4 inches
Find the volume
V = 3.142 * (6.4)^2 * 19.1
= 3.142 * 40.96 * 19.1
= 2458.0997 cubic inches
To nearest tenth
V = 2458.10 cubic inches
The answer to the question is 42ft.
Answer:
PR5T represents <em>6754.</em>
P = 6
R = 7
T = 4
Y = 5
Step-by-step explanation:
Let us try to understand the subtraction starting from the unit's digit.
P R 5 T
- 4 7 Y 6
-----------------
1 9 9 8
To get 8, 6 should be subtracted from 14
14 - 6 = 8
So, T should be equal unit digit of 14 <em>i.e.</em> T = 4 and 1 should be carried over from the ten's digit of PR5T.
Now, let us move to ten's digit:
P R 5 4
- 4 7 Y 6
-----------------
1 9 9 8
To get 9, 6 should be subtracted from 15. But 1 is already carried to unit's place So, we have actually 14 here
14 - Y = 9
So, Y = 5
Moving to hundred's place:
R - carry - 7 = 9
Carry is 1, so R = unit's place of 9 + 8 i.e. R = 7
Moving to thousand's place:
P - carry - 4 = 1
Here carry is 1
So, P = 1 + 4 + 1 = 6
So, the number PR5T is <em>6754.</em>
