A circular lawn has a row of bricks around the edge. The diameter of the lawn is about 40 feet. Which is the best estimate for the total length of the bricks?

The best estimate for the total length of the bricks, using the circumference formula, is: 126 feet.

Given:

Diameter of circular lawn (d) = 40 feet

Required:

Total length of the bricks around the edge of the circular lawn

Applying the circumference formula, plug in the value of d

Circumference = π × 40

Circumference = 126 feet

Therefore, the best estimate for the total length of the bricks, using the circumference formula, is: 126 feet.

125.66 feet

Step-by-step explanation:

To find the total length of the bricks, we can solve for the circumference:

Use the circumference formula, C = 2r

Since the diameter is 40 feet, the radius is 20 feet.

Plug in the radius:

C = 2r

C = 2(20)

C = 125.66

So, the total length of the bricks is approximately 125.66 feet

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
