Answer:

 94.18                            

Step-by-step explanation:

Given in the question a semi circle and a right angle triangle

Step 1

Find the diameter of the semi circle

To find the diameter we will use pythagorus theorem

<h3>hypotenuse² = height² + base²</h3>

here,

hypotenuse will be diameter of semicircle

height = 9

base = 4

Plug values in the formula above

diameter = √(9²+4²)

diameter = √97

Step 2

Find radius

<h3>radius = diameter / 2</h3>

Step 3

Area

<h3>π(r)²</h3>

π(√97/2)²

= 76.18

Step 4

Total surface area = area of circle + area of right angle triangle

                               = 76.18 + 1/2(9)(4)

                               = 94.18

Answer:

y=8x

Step-by-step explanation:

To find the slope, or m, pick 2 points.

I chose (0, 0) and (2, 16)

The use the slope formula

16-0/2-0

16/2

8

to find the y-intercept, or b, find the point where the line crosses the y-axis, which is (0, 0). Take the y-coordinate, which is 0.

So,

y=8x+0

or y=8x
