What is the measure if x?

1 answer:

3 0

The value of x would be 43°. You would find this by breaking up that side of the line into a sum of 180° (a half circle). Then you would do 180°-47°-90°(which accounts for the sum of degrees of the fourth quadrant) and that = 43°.

What is the x value 5x+8-3x=-10

otez555 [7]

5x + 8 - 3x = 10
First you can combine the like terms.
5x - 3x + 8 = 10
2x + 8 = 10
- 8 - 8
2x = 2
$\frac{2x}{2} = \frac{2}{2}$
x=1

The circumference of a bowling ball is 8pi in. Find the surface area of the bowling ball. Express your answer in terms of pi.

MrRa [10]

Surface area of a sphere (3D solid's name for ball shaped object) is given by

$SA = 4 \pi r^{2}$

We do not know the radius of the sphere but we can work it out from the circumference $8 \pi$

$Circumference = 2 \pi r$
$8 \pi =2 \pi r$
$r= \frac{8 \pi }{4 \pi }=2$

then
$SA=4 \pi (2)^{2} =16 \pi$
