Answer: the total area of all the surfaces

Step-by-step explanation:

The surface area of a geometric solid is the area that relates the material that will be used to cover the solid.

When we calculate the surface areas of a geometric solid then we need to find the areas of all its surfaces then add them.

Therefore, the meaning of surface area of a solid described by the total area of all the surfaces.

The correct answer is the total area of all the surfaces.

A solid is a three-dimensional shape. These shapes will have multiple surfaces or curved surfaces. To find the surface area, you would need to find the area of all the surfaces.

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years

forsale [732]

Answer:

$\$13,107.96$

Step-by-step explanation:

Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.

Therefore, we can set up the following equation to find the new balance after 2 years:

$\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}$

ollegr [7]

Using Pythagoras’ theorem a2 + b2 = c2 you can find out the third (longest) side. (6x6) + (8x8) = 100 (the square root of 100 is 10) so ur final sum is 6+8+10 = 24 mm
