Answer:
Width of the Rectangular Tin=8 inch
Length of the Rectangular Tin= 16 inch
Step-by-step explanation:
Let the Width of the Rectangle=W
The length of the piece of tin is twice the width, Length = 2W
Since Squares of 3 inch are cut from all four corners of the rectangle
Length of the box = 2W-(3+3)=(2W-6) inches
Breadth of the Box = W-(3+3)=(W-6) inches
Height = 3 inches
Volume of the box = 60 cubic inches
Now, Volume of a cuboid=lbh
3(2W-6)(W-6)=60
Divide both sides by 3
(2W-6)(W-6)=20
Expanding the brackets
Factorizing
Since the Width cannot be less than 6,
Width of the Rectangular Tin=8 inch
Length= 2 X 8 = 16 inch
Answer: length of arc = 4.71 feet
Step-by-step explanation:
An arc is a portion of the circumference of a circle. The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 2 feet
θ = 135 degrees
Therefore,
Length of arc = 135/360 × 2 × 3.14 × 2 = 4.71 feet
Answer:
3/2
Step-by-step explanation:
b. side = z + 18
c. side = z + 9
Answer:
option c is correct.
side = z+9
Step-by-step explanation:
Area of a square(A) is given by:
where,
s is the side of the square.
As per the statement:
A certain square has an area of
⇒
Substitute in [1] we have;
Taking square root both sides we have;
Using identity rule:
then;
⇒
Simplify:
or
s = z+9
Therefore, a side of the square. is, z+9
