Step-by-step explanation:
Answer:
The distance from the flagpole to the tree is 27 ft
Step-by-step explanation:
The surface area of the sphere is given by the equation
,
where A is the surface area and r is the radius.
We want to find the volume of the sphere, which is given by the equation
,
where V is the volume and r is the radius.
Looking at these equations, we see that they both involve the sphere's radius. If we know what r is, we can calculate the volume.
We know that the sphere's surface area is . Plugging that in for A in the surface area equation, we get
, then divide by
, then divide by 4
, then take the square root of both sides
So the radius of the sphere is 3. Plugging this into the volume equation,
, simplify terms
, multiply by 27
So the volume of the sphere is .
Answer:
Step-by-step explanation:
Just use FOIL (first, outer, inner, last)
3(x + h)(x + h)
First --> (x)(x) = x^2
Outer --> (x)(h) = xh --> 1xh
Inner --> (h)(x) = xh -->1xh
Last --> (h)(h) = h^2
3(x^2 + 1xh + 1xh + h^2)
3(x^2 + 2xh + h^2)
Answer:
1. 3, and 2. m x n
Step-by-step explanation:
1. for an upper triangular 2x2 matrix i.e. (a,0,c,d), three (03) unknown elements a, c, and d are needed to be specified.
2. for m x n matrix, m*n elements are needed to be specified.
