Answer:
3/4
Step-by-step explanation:
54/72 simplified is the same as 3/4
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...

Step-by-step explanation:
cross multiply
2x - 4 = 4 × 5
2x - 4 =20
collect like terms (CLT)
2x = 20 + 4
2x=24
divide both sides by 2
x=12
72 + 72 + 144 + 144 premier is 432 and area is 10368
Answer:
Hypotenuse = 12 inches
Step-by-step explanation:
As the given triangle involves an angle of 90°, this is a right angle triangle.
We an use the Pythagoras theorem to find the length of hypotenuse
So,
Hence the length of hypotenuse is 12 inches ..
