Question

area of circle:diameter=49cm​

Answer 1

Answer:

Area ≈ 1885.74

Step-by-step explanation:

a = π $r^{2}$

d = 2r

Here, diameter = 49cm

Therefore, area of the circle = $\frac{1}{4}$ π = d²

                                               = $\frac{1}{4}$ · π · 49² ≈ 1885.74099

Answer 2

Given

• Diameter of circle = 49 cm

To find

• Area of circle

Solution

• Diameter = 49
• Radius = Diameter / 2
• Radius = 24.5

Hence, the radius of circle is 24.5

• Area of circle = πr²
• Area of circle = 22/7 × 24.5 × 24.5
• Area of circle = 22/7 × 600.25
• Area of circle = 1886.5

Hence, the area of circle is 1886.5 cm²
