For this problem, the answer is choice A.
The volume of a cone is 1/3 times the area of the base times the height.
So the area of the base would be pi times the radius squared, or 3.14 * 3.2^2, which is 32.1536.
Next you multiply 32.1536 by the height(5.8) to get 186.49088.
Then you divide that by 3 to get 62.1636267, rounded to the nearest tenth of an inch is 62.2 inches cubed.
Answer:
8125 mm
Step-by-step explanation:
Not that sure
General form of equation of circle (1),
(x-h)²+(y-k)²=r²....(1)
h=-f=0
k=-g=0
Cause centre is (-f,-g)or (h,k)
here centre is (0,0)
where r is the radius of the circle,
So the general form of equation o f a circle having centre (0,0) is ,
x²+y²=r²
or,x²+y²-r²=0
8q+4=20
8q=16
q=2
hope this helps!
