That looks pretty complicated
24 * 3/4 = 18
The radius of smaller cone is 3/4 the radius of original cone, so since these cones are similar, height must also be 3/4 times smaller.
So since radius is squared and we also multiple the height (V = 1/3 π r² h),
the volume of smaller cone would be 3³ / 4³ = 27 / 64 times smaller
So we have 1920 * (27 / 64) = 810.
Final answer: B
Answer:
the surface area of the decoration is 31.5
Step-by-step explanation:
Answer:
its 16m+2
Step-by-step explanation:
you add m and 15 m because they have the same variable.
then you put the two right next to it
