Hello.
-8.46 is less than 5.31, because it is negative.
X-5y=36
x+y=-26
y=-26-x
x-5(-26-x)=36
x+130+x=36
2x+130=36
2x=36-130
2x=-94
x=47
640/79=8...8
79 goes through 640 8 times
Given.
Radius of the Half sphere is 3 inches.
From the figure;
Radius of half sphere= Radius of cylinder= Radius of cone=3inches
Height of cone= 4inches.
Height of cylinder=6inches.
Volume of cone=(πr²h)/3
=(π3²×4)/3
=(12π) inch³
volume of cylinder= πr²h=π3²6=54π inch³
Volume of half sphere= (4/3) π r³=π(4×3³)/3 (1/2)=π×4×9/2=18π inch³
Total area of Composite figure=(12π +54π +18π) inch³
=84π inch³
=(84)× 22/7inch³
=12×22 inch³
=264inch³
Hope it helps...

Leukonov/Olegion.
Using proportions, it is found that both spaces have the same brightness, as both have 3 candles per m².
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For Nayeli and Citlali, the rate of candles per m² is given by:
- N = 12/4 = 3 candles per m².
- C = 30/10 = 3 candles per m².
Hence both spaces have the same brightness, as both have 3 candles per m².
