Answer:
perimeter=25.12 ft
Area=50.24 ft^2
Step-by-step explanation:
Radius=4 feet
π=3.14
Perimeter=2 x π x Radius
Perimeter=2 x 3.14 x 4
Perimeter=25.12 feet
Area=π x radius x radius
Area=3.14 x 4 x 4
Area=50.24 ft^2
Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
If that is 54.300 the greatest whole number would be 54 if it is supposed to be 54,300 then it would stay the same and be 54,300
Answer:
The order of the differential equation to be formed is equal to the number of arbitrary constants present in the equation of the family of curves.
Consider the equation f ( x, y ,c1 ) = 0 -------(1) where c1 is the arbitrary constant. We form the differential equation from this equation. For this, differentiate equation (1) with respect to the independent variable occur in the equation.
Eliminate the arbitrary constant c from (1) and its derivative. Then we get the required differential equation.
Suppose we have f ( x, y ,c1 ,c2 ) = 0 . Here we have two arbitrary constants c1 and c2 . So, find the first two successive derivatives. Eliminate c1 and c2 from the given function and the successive derivatives. We get the required differential equation.
Note
The order of the differential equation to be formed is equal to the number of arbitrary constants present in the equation of the family of curves.
A and B
Both A and B, when simplified get -(1/6), because the others have either 0 or 2 negative signs, denoting a positive end result.
