Best ResponseYou've already chosen the best response.0it is a circle and the radius is 11ft.

Best ResponseYou've already chosen the best response.0So then the circumference would be 2π(11)ft or 22πft. But there should be an angle measure that corresponds to the arc.

Best ResponseYou've already chosen the best response.0The arc length formula is 2πr*(x/360) where r is the radius and x is the degree measure of the arc.

Best ResponseYou've already chosen the best response.0then you would have 2π(11)(150/360) = 9.167π ft

Best ResponseYou've already chosen the best response.0thanks now i need your help with another question. find the area of a rhombus.

anonymous

Best ResponseYou've already chosen the best response.0so a rhombus is a parallelogram and the area of a parallelogram is base*height. So you should have a base and height. The height will be measured perpendicular to the base (create a 90 degree angle)

Best ResponseYou've already chosen the best response.0a 90 degree angle is already created

Best ResponseYou've already chosen the best response.0Good, then take the base and multiply by the height and that will give you the area.

Best ResponseYou've already chosen the best response.0Are there any lengths given?

anonymous

Best ResponseYou've already chosen the best response.0they gave me 30 and 5cm

anonymous

Best ResponseYou've already chosen the best response.0are these the lengths of the base and the height? If so the answer should be 30*5 = 150 square cm

anonymous

Best ResponseYou've already chosen the best response.0i don't think it is because 150 is not the answer on my answer sheet. I think those numbers represents something else but i just do not know what

Best ResponseYou've already chosen the best response.0Are they the lengths of the diagonals?

anonymous

Best ResponseYou've already chosen the best response.0there are two diagonals and one of the lenghts is 30 and the other number is on the outside of the rhombus.

Best ResponseYou've already chosen the best response.0thanks anyway for trying but im not done with you yet, um I need help with finding the area of a triangle. Round to the nearest tenth and the base of the triangle is 3 ft.

anonymous

Best ResponseYou've already chosen the best response.0ok, area of a triangle is given by the formula (1/2)bh where b is the base and h is the height. So for this problem there should be a height given.

Best ResponseYou've already chosen the best response.0it's only 3ft and its an equilaterial triangle.

anonymous

Best ResponseYou've already chosen the best response.0ah, ok then. In an equilateral triangle you can draw the height in. The height line will cut the base in half and give you two triangles with sides 1.5 and 3 with the last side as 2.59807621 (using the pythagorean theorem a^2 + b^2 = c^2). So the height (2.59807621) times the base (3) divided by 2 is = 3.89711432

anonymous

Best ResponseYou've already chosen the best response.0so are both sides going to be 1.5

Best ResponseYou've already chosen the best response.0how did you get 2.59807621
