Answer:

It is 1,965.74 square feet

Step-by-step explanation:

the area of the circle is πr^2 so if you substitute the variables with the numbers you get, π29^2=841π=841*3.14=2640.74

the area of the triangular flowerbed is 1/2bh=1/2*27*50=675

if you want to find the grass area you would need to subtract the triangular area from the circle, which is 2640.74-675=1965.74 square feet

A red die is tossed and then a green die is tossed. What is the probability that the red die shows a number larger than three or

lianna [129]

Answer:

Red: 67%

Green: 33%

Step-by-step explanation:

Since each die has 6 sides, there is a 1/6 chance for every number.

Probability for a number higher than 3 would be 4/6, which is about 67%.

Probability for below 3 would be 2/6, which is about 33%.

I am not 100% sure, but I hope this helps you.

A helicopter's rotor sweeps out an area of 121 pi square

Nuetrik [128]

Answer:

<h2>22 meters.</h2>

Step-by-step explanation:

It's important to notice that the area is circular, which is defined by

$A= \pi r^{2}$

Replacing given values and solving for r, we have

$121 \pi = \ pi r^{2} \\121=r^{2}\\ r= \sqrt{121}=11$

But, the diameter is twice the radius, so

$d=2r=2(11)=22$

Therefore, the diameter is 22 meters.
