hey the answer is. .
r = 5cm
area = pi r ^2
= 22/7 × 5 × 5
= 78.57 cm^2
circumference = 2 pi r
= 2 × 22/7 × 5
= 31.42 cm
hope it helps uu frnd

Solution:
Given diameter of the circle
(d) = 10cm
i) Area of the circle (A)=(πd²)/4
= π(10)²]/4
= (100/4)π
= 25π cm²
ii ) Circumference (C) = πd
= π×10cm
= 10π cm
