Answer:
The length of the frame is 17
Step-by-step explanation:
The computation of the length of the frame is shown below:
As we know that
The perimeter of a rectangle is
= 2 (length + width)
where,
let us assume the width be x
So, the length is x - 6
And, the perimeter is 80 yards
So, now put these values to the above formula
80 yards = 2 (x - 6+ x)
80 yards = 2 (2x - 6)
80 yards = 4x - 12
92 = 4x
x = 23
So, the length of the frame is
= 23 - 6
= 17
Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 19.79 × 10 × 10 = 1979
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 1979 / 100
Simplifying our fraction
= 1979/100
= 1979/100
= 19 79/100

You asked this second time
Answer:
576cm³
Step-by-step explanation:
The formula for the volumen of a cylinder is given by V = π*r²*h
We are told the diameter is 8cm (r=4cm) and the height is 12cm.
Also, to use 3 as π.
Replacing into the formula, we have:
V = 3*4²*12 = 3*16cm*12cm = 576cm³
I think all you have to do is solve that. 81m squared
