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...

Answer:
124(red) more people favored Florida than New York.
Step-by-step explanation:
38% of 400=152
7% of 400=28
152-28=124
The answer to question is 22.50
Answer:
785.4 units³ (nearest tenth)
Step-by-step explanation:
volume of a cylinder = 
r²h
where r is the radius and h is the height
diameter of a circle = 2r
where r is the radius
Therefore, 10 = 2r ⇒ r = 5
Therefore, volume = x 5² x 10 = 250 = 785.4 units³ (nearest tenth)
The ratio would be 40:1 or 40/1. All you would do is divide the two by numbers that they are divisible until you can't divide anymore and that is your ratio.
