Answer :
- Diameter is 56cm
Given :
- The area of circle is 2464cm²
To find :
- Diameter
Solution :
First we need to find the radius :
As we know that
- Area of circle = πr²
→ Area of circle = πr²
→ 2464 = 22/7 × r²
→ r² = 2464 × 7 / 22
→ r² = 17248/22
→ r² = 784
→ r = √784
→ r = 28
Radius is 28cm
Findings the diameter:
- Diameter = 2r
→ Diameter = 2r
→ Diameter = 2 × 28
→ Diameter = 56cm
Hence , Diameter is 56cm

Answer:
(4) 56 cm
Step-by-step explanation:
By given, Area =2464m²
πd/4 = 2464
d²= 2464 x 4 / 22/7 = 3136
d = √3136 = 56 m
