Answer:
1)461,58sm²
2)53,38sm²
Step-by-step explanation:
p=3,14
1) r=14sm
p×r²=14²×3,14=615,44
S1=615,44
r=7sm
p×r²=7²×3,14=153,86
S2=153,86
The painted surface of the circle:
S1-S2=615,44-153,86=
461,58
2) r=9sm
p×r²=9²×3,14=254,34
S1=254,34
r=8sm
p×r²=8²×3,14=200,96
S2=200,96
The painted surface of the circle:
S1-S2=254,34-200,96=53,38
Answer:
1)461,58sm²
2)53,38sm²
