Answer:

1. Please find attached the drawing of triangle of side 4 units each created with MS Whiteboard

2. The vertices of the created triangle are labelled SUN

3. The measure of the angles using a protractor are ∠S = 60°, ∠U = 60°, and ∠N = 60°

4. Please find attached the drawing of the extension of SN to the point Y created using the Inking mode on MS Whiteboard

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra

luda_lava [24]

The surface area of a sphere is $A = 4 \pi r^{2}$ and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.

For example, let us assign values.
Let A=90

A= 90*9 = 810

$90 = 4 \pi r^{2} 

$ and $810 = 4 \pi r ^{2}$

the first r is 2.68 and the second r is 8.03

then, $\frac{8.03}{2.68} = 2.99626$ or rounded off to 3.

If a dart were thrown randomly at the dart board shown below, what is the

klemol [59]

Answer: A. 31%

Step-by-step explanation:

First you need to find the area within each circle. This can be found by using the formula: pi * r^2

The area of the circle with radius 8mm is 64 * pi. The area of the circle with radius 14mm is 196 * pi.

196 * pi = 615.75216

64 * pi = 201.06193

Now divide the larger area by the smaller area to get how many times larger the large area is than the small area.

615.75216 / 201.06913 = 3.06239

3.06239 rounds up to 3.1

Now we know the radius of 14mm has an area 3.1 times the area of 8mm. The area of an 8mm radius has 31% of the area of a 14mm radius.
