Answer 1

Ответ:

a) R=4; C=25,12

б) R=8; d=16; S=200,96

в) R=8,5; C=53,38; S=226,865

Объяснение:

S=50,24;

S=πR²; → R=√(S/π)=√(50,24/3,14)=√16=4

C=2πR=2*4*3,14=25,12

_______________

C=50,24

C=2πR; → R=C/2π=50,24/(2*3,14)=8

d=2R=2*8=16

S=πR²=3,14*8²=200,96

________________

d=17

R=d/2=17/2=8,5

C=dπ=17*3,14=53,38

S=πR²=3,14*8,5²=226,865
