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
Answer:
A. 62.8 in.
Step-by-step explanation:
Circumference of a circle = πd
Diameter (d) = 20 in.
Substitute
Circumference = π × 20
Circumference = 62.8318531
Circumference = 62.8 in. (Approximated to nearest tenth)
Answer:
The answer is A, "Find the number of 1 foot cubes that fill the fish tank."
Step-by-step explanation:
You can find the answer by multiplying 3 x 3 x 5, which is 45. 45 1 foot cubes will fill the fish tank.
Answer:
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount
Substitute 
for A in
Substitute 
for F in
The total amount is calculated by adding the earnings of Alice, her friend and you
<em>Hence, the total earnings is 5d - 2</em>
