Answer:
Step-by-step explanation:
The area of a circle is pi multiplied by the radius squared: .
The figure shows a diamater equal to 14 m, so the radius is half of that, 7 m.
A calculator gives a decimal approximation of 153.94 meters squared. (
Answer:
1/625
Step-by-step explanation:
When you multiply, you add the exponents. You now have . This is equivalent to which equals 1/625.
Answer: The line has a slope of 1
Step-by-step explanation:
Look at the attachment
Volume of the cone = 1/3 pi * 3^2 * 4 = 12pi
Volume of the hemisphere = 4/3 pi 3^3 * 1/2 = 18pi
So the volume of the toy = 12pi + 18pi = 30pi = 94.25 cm^3 to nearest hundredth Answer
Surface area of hemisphere = 1/2 * 4 pi 3^2 = 18pi
Lateral Surface area of the cone = pi r l where l = slant height of the cone
Now l= sqrt ( 4^2 + 3^2) = sqrt25 = 5
So lateral S A = 3 * 5 * pi = 15pi
Surface area of the toy = 18pi + 15pi = 33pi = 103.67 cm^2 ( nearest hundredth) Answer
To start, we know the basic equation from what us given:
And we want to find m. Fortunately, we have some numbers to plug in to find m. We can make an equation like this
by taking the amount charged and the amount of miles driven to get that charge given in the original problem.
Now we solve.
Now we can put that in our equation to finish it.
And that is the final equation
