Answer:

m = 2root2 or -2root2

Step-by-step explanation:

See the attached graph. We know that it can't be greater than 3, otherwise there are two solutions, and it can't be less than 2, otherwise there are no solutions. The only thing that works is either 2root2 or -2root2. (Root stands for square root.)

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for ∏.
bogdanovich [222]

Answer:

66

Step-by-step explanation:

The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. What is the maximum number of square feet of lawn mr. Ri
zaharov [31]

Answer:

Step-by-step explanation:

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. The formula for determining the area of a circle is expressed as

Area = πr²

Where

π is a constant whose value is 3.14.

r represents the radius if the circle.

The area covered by one of Mr. Rives' rotating sprinkler would be

3.14 × 7² = 3.14 × 49 = 153.86ft²

Therefore, the maximum area of lawn that two sprinklers can cover would be

153.86 × 2 = 307.72 ft²
