Answer: (a,a)
Step-by-step explanation:
Given: A right isosceles triangle which is placed on the coordinate plane such that one of the legs of the triangle lies along the x-axis and the other leg is parallel to the y-axis.
From the given figure one vertex is on origin(0,0) and second on x -axis as (a,0) .ii.e. one side of the triangle is on the x axis with length 'a' and the side parallel to the y axis should perpendicular to the x axis with length 'a'.(∵ two sides are equal in a right isosceles triangle)
So the coordinates should she assign to the third vertex of the right isosceles triangle is (a,a).[as the point lie above the point (a,0), so its x abscissa should be same]
Answer: 340 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference = 2π radius
Replacing with the circumference value and solving for r:
31.416 =2π r
31.416 /2π =r
5cm =r
And then:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
V = 1/3 π (5)^2 (13) = 340 cm3
Feel free to ask for more if needed or if you did not understand something.
Volume of the toy bouncy ball:
V = 4/3 r³ π
4.19 = 4/3 r³ · 3.14
r³ = ( 4.19 · 3 ) : ( 4 · 3.14 ) = 1
r = ∛1 = 1 in
Volume of the cube: V = a³
There are 64 toy balls. It means that there are 4 x 4 x 4 in the cube.
a = 4 · 2 r = 8 in
V = 8³ = 8 · 8 · 8 = 512 in³
Answer: B ) 512 in³
