Question

find the circumference and diameter of a circle whose radius is 35 cm

Answer 1

Answer:

Diameter=2×Radius=2×35=70cm

Circumference= πd = 70π cm

Answer 2

Answer:

Diameter=70cm

Circumference=

Step-by-step explanation:

d = 2r

d = 2×r

therefore, d = 2×35cm

thus, d = 70cm

circumference =

$\pi \: r^{2} \\ = 22 \div 7 \times r \times r \\ = 22 \div 7 \times 35 \times 35$
