Answer:
(i) 14.96cm
(ii) 22.4cm
(iii) 126cm
Step-by-step explanation:
area of a circle is πr²
substitute each question
(i) 176 = 22/7×r²
r² = 176×7/22
= 56
r = √56
= 7.48cm
d = 7.48 + 7.48 (diameter is double the radius)
= 14.96cm
( this is the answer i think, you can do the other ones just lik this )
