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...

If it is a straight line going across then the slope is 0.
Answer:
a(n) = a(n-1) + 4
Step-by-step explanation:
a(1) = 2 The first term is 2
a(n) = a(n-1) + 4 We add 4 to the previous term or n-1
So, we get...
a(n) = a(n-1) + 4
a(1) = 2
a(2) = a(2-1) + 4 2(1) +4 = 6
a(3) = a(3-1) +4 3(2) + 4 = 10
and so on and so forth. I hope this helps.
