Answer: Area of sidewalk is 217m²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle
π is a constant whose value is 3.14
A circular flower bed is 20 meters in diameter.
radius = diameter/2 = 20/2 = 10 meters
Area of the flower bed = 3.14 × 10²
= 314m²
The circular flower bed has a circular sidewalk around it that is 3 meters wide. This means that the total diameter would be
3 + 20 + 3 = 26m
Radius = 26!2 = 13m
Total area = 3.14 × 13² = 530.66m²
Therefore, area of the sidewalk is
530.66 - 314 = 216.66
The area of sidewalk is 217m² to the nearest whole number
Step-by-step explanation:
slope is y2-y1/x2-x1
formula is
y=mx+b where m is the slope
Answer:
The babies massed in total 7.41 kg
Step-by-step explanation:
we know that
To find out the total mass, sum Adrian's mass and Chang's mass
so
The total mass is equal to
therefore
The babies massed in total 7.41 kg
