Answer:
Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.
Step-by-step explanation:
Given:
2 kg of taronges and 3 kg mandarins cost 11.5 euros
3kg taronges and 2 kg mandarins cost 11 euros
To Find:
Price for each product
Solution:
<em>Consider </em>
<em>Taronges =x euros</em>
<em>Mandarins=y euros</em>
So by given condition,
....................equation(1)
and
...........equation (2)
So , using substitution method,

.......equation (3)
Using above value in equation(1) we get ,

)
y=2.5 euros
Using above value in equation(3) we get ,



x=2 euros
S=4π<span>r<span>2 - this is the equation for the surface area of a sphere. We know that the radius (r) is 3.5 so here's how to solve this:
S = 4</span></span><span>π r2
S = 4</span><span>π (3.5)2
S = 4</span><span>π 12.25
S = 49</span><span>π
The surface area of a sphere with radius of 3.5 is 49</span><span>π.</span>
