This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m
The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm
Answer: 3x -4
Step-by-step explanation:
Okay. first multiply 16*6*8. that's the volume of the prism that's standing. then do 16*16*4. that's the one on the left. now do 14*14*14. that's the one on the right. add all of them up and you should get 4,536 cm^3

Step-by-step explanation:
The formula for finding the area of a circle is;
![A = (pi)r^2](https://tex.z-dn.net/?f=A%20%3D%20%28pi%29r%5E2)
Where (
) represents the area of the circle, (
) represents the value (
) and (
) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.
This means that the radius for the given circle is (
), since (
÷
)
Substitute these values into the equation and solve for the area of the circle.
![A = (pi)r^2\\\\A = (pi)(2.5)^2\\\\A = (pi)6.25\\](https://tex.z-dn.net/?f=A%20%3D%20%28pi%29r%5E2%5C%5C%5C%5CA%20%3D%20%28pi%29%282.5%29%5E2%5C%5C%5C%5CA%20%3D%20%28pi%296.25%5C%5C)
