You add 1. 19 divided by 4... it’s not a full number. (Whole number). But, 19 plus 1 equals 20. 20 divided by 4 is 5
Answer:
Sorry, it's gonna be 0.97, and you just add 0.12 to 0.25 7 times. This is the right answer.
Step-by-step explanation:
22+19=<span>41
41/70= </span><span>0.5(simplified)</span>
I’m here to help.
For this question here you need to use the sine formula for the area of a triangle and figure out the area of the sector
I’ll take you through it step-by-step
Area of the arc:
We only have 68.9 degrees out of 360 and we need to use the formula for the area of a circle.
Formula of a circle = pi x radius squared
68.9/360 x pi x 86.1184= 51.78 (2dp)
Area of triangle:
As you can see we have no height so we must use the sine formula for the area of a triangle.
Formula= 1/2abSinC
You should end up with
0.5 x 9.28x 9.28 x Sin(68.9)= 40.17 (2dp)
Now since you want the area of the segment shaded, just find the difference between these two values.
51.78-40.17 = 11.61
Answer= 11.6cm squared
Hope this helped!
Answer : -0.5
Explanation: because it’s a negative number and is less than 0 is it cannot represent a probability of an event.
