Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
Hey there!!
Let's take a closer look at the question,
We have the original price with included 15% tax
This original price is first reduced by 35% , first let's solve this.
35% = 35 / 100 = 0.35
0.35 × 1899
... $664.65 = 35% of of $1899.00
It would be sold for
... 1899 - 664.65
... $1234.35
Now, this price is further reduced by 20%
20% = 20/100 = 0.20
... 0.20 × 1234.35
... $246.87
This is 20% of 1234.35
Now, the price it would be sold for =
... $1234.35 - $246.87
... $987.42 is the final price the sofa would be sold for.
Hope my answer helps!!
Answer:
That's great for you. I hope u got your answers
Answer:
let the scone be x and the large coffees be y.
7x+4y=$25.76-----equ(I)
2x+5y=$14.92-----equ(2)
make x the subject of the formulae in equation(ii).
x=$14.92/2-5y
x=7.46-5y
D = sqrt(3s^2) where s is the length of the side. Solving for s,
<span>3s^2 = d^2 iff </span>
<span>s^2 = d^2 / 3 iff </span>
<span>s = sqrt(d^2 / 3) </span>
<span>= d / sqrt(3) or d sqrt(3) / 3 </span>
<span>Surface area of the cube = 6 s^2. Thus, </span>
<span>A = 6 (d / sqrt(3))^2 </span>
<span>= 6d^2 / 3 </span>
<span>= 2d^2 </span>
<span>Volume = s^3. Thus, </span>
<span>V = (d / sqrt(3))^3 </span>
<span>= d^3 / 3sqrt(3) </span>
<span>= d^3 sqrt(3) / 9</span>
