Answer: 11.1 m
Step-by-step explanation:
This can be solved by the Pythagorean theorem where;
c² = a² + b²
c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.
a is the height
c is the length
32² = 30² + b²
b² = 32² - 30²
b² = 1,024 - 900
b² = 124
b = √124
b = 11.1 m
The absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.

Answer: R=2.75
Step-by-step explanation: How to find the radius of a sphere?
This question seems very easy at first. You only have to find the center of the sphere and measure the distance to any point on its surface. However, how can you find this center in real, physical sphere, especially when it's closed? Let's look on a two of my suggestions:
Find the diameter. You can use two parallel planes and put the sphere between them. The distance between those plates equals the diameter of a sphere.
Find the volume. Prepare a graduated cylindrical container filled with water. Put a sphere into this cylinder, then bring out the sphere and measure the volume of displaced water
Answer:
a = 18/b²
Step-by-step explanation:
Step 1: Write equation
1/3ab² = 6
Step 2: Solve for <em>a</em>
- Multiply both sides by 3: ab² = 18
- Divide both sides by b²: a = 18/b²
