10•4=40. 40 is the perimeter of the square. To find the perimeter of the semicircle use the circle perimeter (circumference) formula and divide that answer by two. This would be pi•10. You get 31.4. Then divide by 2 so it’s 15.7. Finally add 15.7 and 40. Hope this helps... sorry it’s such a long answer
Answer:
340 degrees
Step-by-step explanation:
So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).
So the circumference of a circle = 2pi(r)
This means:
6 = 2pi(r)
Which means that
r = 6/2pi or r = 3/pi
Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:
Arc length is defined by: length = θr
Where θ is our angle value.
So lets plug in:

Multiply by pi to get:

Divide by 3 to get that:
θ = 17pi/9
So if we convert that from radians to degrees we get 340 degrees.
The answer to the problem is going to be 3
Answer:
x= 41.8°
Step-by-step explanation:
use inverse trig to find x.
(
)=x
type this into your calculator. (make sure the mode on your calculator is degree or it won't work)
x= 41.8
Hope This Helps:)

Jordan spends 50 minutes on his homework.
Step-by-step explanation:
Given,
Time spent on Maths homework = 11 minutes
This represents the 22% time of his total homework.
Let,
x be the total time spent on homework.
22% of x = 11

Dividing both sides by 0.22

Jordan spends 50 minutes on his homework.
