Question

find the circumference and area of a citcle whise diameter is 88 cm​

Answer 1

Answer:

circumference=276.46 cm and area=12,164.24 cm^2

Step-by-step explanation:

circumference=2pir=2*3.14*44=276.46 cm

area=2pir^2=circumference*r=12,164.24 cm^2

Answer 2

Taking the value of π = 3.14

Circumference of circle = 276.32 cm

Area of circle = 6,079.04 cm²

___________________________

Taking the value of π = 22/7

Circumference of circle = 276.571428571 cm

Area of circle = 6084.57142857 cm²

Step-by-step explanation:

GIVEN

Diameter = 88 cm

Radius = Diameter / 2 = 88 / 2 = 44cm

π = 3.14 or 22/7

___________________________

Taking the value of π = 3.14

We know that

Circumference of circle = 2πr

Circumference of circle = 2 × 3.14 × 44

Circumference of circle = 276.32

Circumference of circle = 276.32 cm

___________________________

We know that

Area of circle = π r²

Area of circle = 3.14 × (44)²

Area of circle = 3.14 × 1936

Area of circle = 6,079.04

Area of circle = 6,079.04 cm²

___________________________

Taking the value of π = 22/7

We know that

Circumference of circle = 2πr

Circumference of circle = 2 × 22/7 × 44

Circumference of circle = 276.571428571

Circumference of circle = 276.571428571 cm

___________________________

We know that

Area of circle = π r²

Area of circle = 22/7 × (44)²

Area of circle = 22/7 × 1936

Area of circle = 6084.57142857

Area of circle = 6084.57142857 cm²
