Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie

240.6 m²

Step-by-step explanation:

Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie

Step 1

We have to find the radius of the circular fence

The circumference of a circle = 2πr

Circumference = 55m

Hence:

55m = 2 × 22/7 × r

55 = 44/7

r = 55 ÷ 44/7

r = 55 × 7/55

r = 8.75m

Step 2

We find the approximate area in square meters of the section.

Area of a circle = πr²

Area of the circle = 22/7 × 8.75²

Area of the circle = 240.625 m²

Approximately = 240.6 m²

Therefore, the approximate area in square meters of the section is 240.6m²

answer: about 22.67

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
