A neighborhood park is circular in shape. One sector of the park needs repairing, so officials would like to block off that port

ion with barricades. The area of the sector is 45 yd2, and o=72. Find the length of one side of the barricades (i.e., the radius of the circle).

I will assume that 0 =72 refers to that the angle of the sectoris 72°.

If so, this sector represents 72°/360° = 1/5 of the total circle.

Then the area of the total circles is 5 * 45yd^2 = 225 yd^2

The radius is obtained from:

Area = π(r^2) = 225 yd^2

r^2 = 225 yd^2 / π = 71.62 yd^2

r = √(71.62yd^2) = 8.5 yd

Answer: 8.5 yd

What is the surface area of the box if it is scaled up by a factor of 10? THE SURFACE AREA IS 432CM. LEGHT 12CM. WIDTH 6CM. HEIG
marissa [1.9K]

The scale factor for area is the square of the scale factor for linear dimensions. If linear dimensions are scaled up by a factor of 10, the area is scaled up by a factor of 10² = 100.

The area of the larger box is 100×432 cm² = 43,200 cm².

What’s the answer and how do I solve it?
Dimas [21]

Answer:

x= -1, x=3

Step-by-step explanation:

The “zeros” of a quadratic function are where the parabola intersects the x axis. In that graph the parabola touches x=-1 and x=-3. Therefore that is the answer.

Help!!!!!!!! i have no clue

Answer: Non-proportional

Step-by-step explanation:

The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70

So...you know that it is not proportional
