What is the radius of the field? * a circular field has a area of 14400 sq ft

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
8 0

Answer:

r = 67.70 feet

Step-by-step explanation:

Area of circle, A = πr²

where r is the radius and π = 3.142

A = πr²

r² = A / π

r = √(A / π)

r = √(14400 / 3.1042)

r = √(4583.66)

r = 67.70 feet

I’m studying for my Sat later in the month, and even using the answer key I don’t understand how to solve this question. Help?
shepuryov [24]

So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 96\pi =24\pi +x(\frac{4}{3}\pi*3^3)

Firstly, solve the parentheses: 96\pi =24\pi +x(\frac{4}{3}\pi*27)\\ 96\pi =24\pi +x(36\pi)

Next, multiply 36 pi and x: 96\pi = 24\pi +36\pi x

Next, subtract 24 pi on both sides: 72\pi =36\pi x

Lastly, divide both sides by 36 pi, and your answer will be 2=x, or B.

Step-by-step explanation:

B. With hawaii airline = -0.300

Without hawaii airline = 0.197

With hawaii airline

EX = 475.3

EY = 157.17

XY = 8042.11

X² = 26883.55

Y² = 3159.375

The correlation coefficient

= 72378.99-74702.9/7737.421

= -2323.91/7737.421

= -0.300

Without hawaii airline

EX = 396.9

EY = 152.11

EXY = 7645.406

X² = 20736.99

Y² = 3133.772

= 790.789/4021.161

= 0.197
