2.25, 2, 4.75 I am not sure if it is correct tho
Step-by-step explanation:
the frist row shows 5 6 so basically it would be r = y + 1 (red paint being r and yellow paint being y)
1.25 + 1 + 2.25
3 - 1 = 2
3.75 + 1 = 4.75

Answer:
27p4-27p2-12p+12/p
Step-by-step explanation:
Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
