Answer:
125.6m^2
Step-by-step explanation:
Let R be the greater radius and r be the smaller radius
Area of the sidewalk = R^2 - r^2 - This can be the expression
= 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
= 40
= 3.14 x 40
Answer:
Step-by-step explanation:
volume of box=6×6×7 in³
he fits gold 2×2×2
so he fits it in 6×6×6
so number of gold boxes=(6×6×6)/(2×2×2)=27
remaining space=1×6×6
number of silver boxes=(1×6×6)/(1×1×1)=36
total boxes he took=27+36=63
Answer:
Slope is -2
Step-by-step explanation:
( -3, 7) and ( -2, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-7)/(-2+3)
m = (-2)/1
m = -2
