Question

Maths 10th question with full explanation

Answer 1

perimeter =44

we know that perimeter =2×22/7×r
2×22/7×r=44
r=44×7/22
r=14
area of circle=22/7×14square
22/7×196
22×28
Ans=616

Answer 2

Answer:

154 cm²

Step-by-step explanation:

Perimeter of Circle = 44 cm

We know that Perimeter of circle = circumference = 2π(radius)

∴          2 × π × radius = 44

    2 × (22/7) × radius = 44

                        radius = (44 × 7) / 44

                        radius = 7 cm

Now,

Area of Circle = π × (radius)²

                        = (22/7) × (7)²

                        = 154 cm²

∴ Area of Given Circle is 154 cm²
