Answer:
Step-by-step explanation:
Let the width of the rectangle = x
Length = 2x
Perimeter = 96 inches
2 * ( length + width) = 96
2 * ( 2x + x ) = 96
2 * 3x = 96
3x = 96/2 = 48
3x = 48
x = 48/3
x = 16 inches
Width = 16 inches
Length = 2*16 = 32 inches
Area = length*width
= 32*16
= 512 sq.cm
Think about it think 6x5 or higher then you will get you answer by doing that
Use the Pythagorean theorem since you are working with a right triangle:
a^2+b^2=c^2a2+b2=c2
The legs are a and b and the hypotenuse is c. The hypotenuse is always opposite the 90° angle. Insert the appropriate values:
0.8^2+0.6^2=c^20.82+0.62=c2
Solve for c. Simplify the exponents (x^2=x*xx2=x∗x ):
0.64+0.36=c^20.64+0.36=c2
Add:
1=c^21=c2
Isolate c. Find the square root of both sides:
\begin{gathered}\sqrt{1}=\sqrt{c^2}\\\\\sqrt{1}=c\end{gathered}1=c21=c
Simplify \sqrt{1}1 . Any root of 1 is 1:
c=c= ±11 *
c=1,-1c=1,−1
Answer:
V =113.04 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = 3.14 (3)^2 4
V = 3.14 *9*4
V =113.04 cm^3
