$\qquad\qquad\underline{\textsf{\textbf{ \color{magenta}{Solution\:completed} }}}$

Given that circumference of circle = 154 m

i.e 2 π r = 154

⇒ r = 154 / 2 π

⇒ r = 154 x 7 / 2 x 22.

⇒ r = 49 / 2

= 24.5 m

∴ radius of circle = 24.5 m

Area of circle A = π r2

A = π x 49 / 2 x 49 / 2

= 3773 / 2

= 1886.5 m2

Answer 2

Step-by-step explanation:

Answer:-

Given that circumference of circle = 154 m

• i.e 2 π r = 154
• ⇒ r = 154 / 2 π
• ⇒ r = 154 x 7 / 2 x 22.
• ⇒ r = 49 / 2
• = 24.5 m

∴ radius of circle = 24.5 m

Area of circle A = π r2

A = π x 49 / 2 x 49 / 2

• = 3773 / 2
• = 1886.5 m2
