1/y - 1/x = 1/60<br> 3y - 2x = 6 <br> (Simultaneous question)

Daniel [21]

1y - 1/x = 1/60 = x*y =60 = x=60/y

3y - 2(60/y) = 6

3y^2-120=6y

3(y^2-40-2y) =0

y^2-40-2y=0

y = 7.4

3(7.4)-2x=6

22.2-2x = 6

2x = -16.2

x = -8.1

What is the area of d=8 and r=4

Alex

So, for the semi circle, we need to find the area of a circle then divide it by 2.

pi times r squared

$\pi 16$ is the area of a circle with the radius of 4

(I'm going to use 3.14 as pi)

So 3.14 times 16 is 50.24

Divide that by 2 and we get 25.12

For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.

8 times 8 is 64.

To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12

So the area is 89.12 feet squared.

Any questions?
