Question

find the radious and diameter of circle that has an area of 145cm2​

Answer 1

Answer:

Step-by-step explanation:

  r=23 cm

 d= 46 cm

Answer 2

Answer:

Area of a circle =πr^2

145=22/7*r^2

145*7/22=r^2

1015/22=r^2

46.1363=r^2

√46.1363=r

r=6.79

Therefore r= 6.79.

d=2*6.79

d=13.58.

So radius is 6.79(approximately)

Diameter is 13.58(approximately)
