Answer:
you will get the same answer its just that one equation is the other way around
Area of a circle = pi * r^2
A = (3.14) * 8^2
A = 3.14 * 64
A =200.96 units ^2
Answer:
the third one
Step-by-step explanation:
Answer:
12 is the answer.
Step-by-step explanation:
The best way to get the roots of the equation is to factorize the equation but when the factors are not possible then we should apply the quadratic equations formula to get the value of x.
Now we will try to factorize
x² - 8x -48 = 0
Now we multiply coefficient of highest degree term and constant term
48×1 = 48 which may be factored in 12×4. 8×6, 24×2.
Now we will choose 12×4 out of three because the 12-4 = 8 which is the coefficient of x.
Now its simple.
x²-12x + 4x -48 = 0
x(x -12) + 4(x-12) = 0
(x +4)(x-12) = 0
Therefore roots are x + 4 = 0
x = -4
and x - 12 = 0
x = 12
So the answer is 12.
Answer:
1131 cubic inches.
Step-by-step explanation:
The front side of the figure contains a rectangle and a semicircle.
Area of rectangle is
Radius of semicircle is
Area of semicircle is
Area of front side is
Let front side is the base of prism and height is 6 in. So, volume of given figure is
Therefore, the required volume is 1131 cubic inches.
