Answer:
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
Where "l" is the length and "w" is the width.
The area of a triangle can be found using the following formula:
Where "b" is the base of the triangle and "h" is the height.
You can observe that the figure is formed by three different rectangles, Using the formulas, you ge that the area of each rectangle is:
The triangles are equal, then, using the formula shown above, you get that the area of each of them is:
Adding all the areas, you get that the surface area of the figure is:

Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
The general form of an equation of a circle:
We have the center (-2, 1). Substitute to the equation in the standard form:
Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:
Therefore we have the equation:
Convert to the general form.

Answer:
Step-by-step explanation:
Given volume as a function of time is for a ball is V(t) = 10t
we know that volume of a sphere is given by
where r is radius of sphere
Note we are using formula for sphere as ball is spherical in shape
Now equating volume V(t) = 10t, and volume of a sphere is given by formula
Hence radius at a given volume can be modeled by function
