Circle = pi*r^2
Diameter = 80, so radius = 40
Circle = pi*40^2 = pi*1600 is approximately 5026.55 yards
Answer: the answer is: 60π in²
Step-by-step explanation:
Lateral surface area for a circular cone is given by the formula in the attached picture.
Lateral Surface Area,
=πr √( r² + h²)
=π (6) √( 6² + 8²)
= π6 √( 36 + 64)
= 6π √(100)
= 6π (10)
= 60π in²
Answer:
6
Step-by-step explanation:
54 divided by 9 = 6
Answer:
3
Step-by-step explanation:
4f-3 = 5f-6
First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides
4f -3 = 5f -6
+6 +6
Making it into: 4f + 3 = 5f
Now to get the 4f on the other side we will have to subtract it from both sides
4f +3 = 5f
-4f -4f
3= f (Remember you do not have to put the 1, making 3 your answer)
We have been given that side length of pyramid the square base is 12 cm and its slant height is 10 cm. We are asked to find the height of the pyramid.
We will use slant height of a pyramid formula to solve our given problem.
,where,
s = Slant height,
h = Height,
a = Each side of square base.
Upon substituting our given values in above formula, we will get:
Switch sides:
Let us square both sides:
Now we will take positive square root of both sides.
Therefore, the height of the pyramid is 8 cm and option 'b' is the correct choice.
