I'm pretty sure that the answer is A., because if you turn the fraction into a decimal and multiply it by 24, you get 7.999992, which estimates to be 8.
Answer:
A = 225 pi cm^2
Using 3.14 for pi
A =706.5 cm^2
Using the pi button for pi
A =706.8583471 cm^2
Step-by-step explanation:
The area of a circle is
A = pi r^2
A = pi (15)^2
A = 225 pi cm^2
Using 3.14 for pi
A =706.5 cm^2
Using the pi button for pi
A =706.8583471 cm^2
1. y=6
2. y=-12
Step-by-step explanation:
<u>1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.</u>
It is given that
y varies inversely as x
IT will be written as:
y∝1/x
Removing the proportionality symbol
y=k/x
Given
y=3 , x=-2
Putting the values
3=k/-2
k=3*-2 = -6
The equation will be:
y=-6/x
So,
When x=-1
<u>2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4</u>
y is directly proportional to x
y∝x
y=kx
Given
y=15, x=-3
Putting the values
Hence,
1. y=6
2. y=-12
