Question

what is the area and circumference of a circle with a diameter of 14 metres

Answer 1

Diameter of circle = 14 m

Radius of circle = 14 /2 = 7 m

Area of circle = pi r^2

= 22 × 7 × 7 / 7

= 22 × 7

= 154 m^2

Circumference of circle = 2 × Pi × r

= 2 × 22 × 7 / 7

= 2 × 22

= 44 m

Answer 2

d=14m
 
r=d/2       r=14/2       r=7m

A=πr²
 =π*7²

A=49π m²

S=2πr
 =2*π*7
 S=14π
 hope it helpfull
