The area of the circular shaped patio is: 172.7 ft²

<h3>What is the Area of a Circle?</h3>

Area of a circle = πr² [r is given as the radius of the circle].

The area of the patio = area of the larger circle - area of the smaller circle.

Radius of the larger circle = 8 cm

Radius of the smaller circle = 3 cm

π = 3.14

Area of smaller circle = πr² = (3.14)(3²)

Area of smaller circle = 28.26 cm²

Area of bigger circle = πr² = (3.14)(8²)

Area of bigger circle = 200.96 cm²

The area of the patio = 200.96 - 28.26

The area of the patio = 172.7 ft²

Answer:

volume of sphere = 288π ft³

Explanation:

volume of sphere = $\frac{4}{3} \pi r^3$

where pi is a constant and r is the radius of the sphere

We are given that:

The diameter of the sphere is 12 ft.

This means that the radius = $\frac{12}{2} = 6 ft$

Substitute with the radius in the above equation to get the volume as follows:

volume = $\frac{4}{3} \pi *(6)^3 = 288\pi$ ft³

Hope this helps :)

The point (5, −2) is on the terminal ray of angle θ, which is in standard position. Without evaluating, explain how you would fi

Anni [7]

1. Check the picture attached.

let P, M, N be the points :P(5, -2), M(5, 0), N(0, -2)

ABP is the angle with measure ∅, where BA is the initial ray and BP the terminal ray.

2. m(PNM)=∅ as can be easily checked

In triangle PNM, NP=5, PM=2 and NM= $\sqrt{ 5^{2} + 2^{2} }= \sqrt{25+4}= \sqrt{29}$ units

3. let opp=opposite side, adj=adjecent side, hyp=hypothenuse

sin ∅ = opp/hyp= $\frac{2}{\sqrt{29}}$

cos ∅ = adj/hyp= $\frac{5}{\sqrt{29}}$

tan ∅ = opp/adj=2/5

cot ∅ = adj/opp=5/2

sec ∅ = hyp/adj= $\frac{\sqrt{29}}{5}$

csc ∅ = hyp/opp= $\frac{\sqrt{29}}{2}$

When using the vertical line test the vertical line can only go through the graph ____ times for it to be a function.

tresset_1 [31]

Answer:

once

Step-by-step explanation:

The vertical line test shows how many outputs (y-value) there are for one input (x-value). There can only one output for each input because only one value should satisfy an equation that represents a function. If the vertical line goes through the graph twice, that shows there are two outputs for a single x-value. This would mean it is not a function.
