Answer:

The formula for calculating the circumference (C) of a circle, C = πD or C = 2πR, is simple if you know the circle's diameter (D) or radius (R). But what do you do if you only know the circle's area? Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle's circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.

If Bill bought a home for $210,000 and he sold it a year later for $120,000 his percentage of loss is

Greeley [361]

Answer:

Bill suffered a loss of 42.85%.

Step-by-step explanation:

Bill bought a home for $210000 and sold it for $120000 and we have to calculate the percentage loss he suffered.

As we know loss suffered = Difference of sale price and cost price of the home.

Total loss = 210000-120000 = $90000

Now percentage loss = $\frac{Total Loss }{cost price}.(100) = \frac{9000}{210000}.(100)$

= 9/21×100 = 3×100/7 = 42.85%

So the answer is 42.85% loss.

Explain the difference between the slant height of a pyramid and the height of the pyramid.

dexar [7]

See the diagram below.
$h$ is the height, and $s$ is the slant height.

The height is the distance from the base of the pyramid to the vertex (the top of the pyramid). It runs perpendicular to the base.

The slant height is the distance from the base of the triangles which make up its sides to the vertex. It runs perpendicular to this base as well.
