False, you want to subtract in order to get rid of the 2x in both equations
Polygons are 2D shapes with straight sides. Quadrilaterals are polygons with four sides.
Trapezoids, rectangles, squares and parallelograms are all quadrilaterals as they have four sides.
Not all polygons are quadrilaterals.
Answer:
V = 286319.465 cm3
Step-by-step explanation:
First, you have to find the radius to be able to find the volume of a sphere.
The equation for the area of a circle is pi r^2 so you have to so some algebra.
5252 = pi r ^2
5252/pi = r^2
1671.76352 = r^2
sqrt(1671.76352) = r
r = 40.8872048
then you do the equation for the volume of a circle which is 4/3 pi r^3
4/3 pi (40.8872048)^3
4/3 pi 68353.7373
4/3 214739.599
286319.465
V = 286319.465 cm3
Answer:
J. 36 Days
Step-by-step explanation:
60÷5 = 12
3×12 = 36
[Insert generic name here] is trying to bake a yellow cake because [reasons]. This recipe will make one whole cake.
He wants to make three cakes instead of one. How much of each item should be used in the new (scaled-up) recipe?
I don't know exactly how your teacher wants you to write out the work, but I have it pretty simple there. It's not like math is tailored to a specific process; any sort of reasonable work should do.
Good luck!
