Answer:
180
Step-by-step explanation:
4 times 20 is 80, and 4 times 5 is 100, so add those together and that's the total number of coins
This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!
Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in
