Answer:
215.20 ft^2
Step-by-step explanation:
The figure has 2 semi-circles.
First we find the area of each circle using the formula
because that is the area formula for a circle.
The semi-circle to the left gives the diameter which is 22 feet. The radius would be half the diameter thus r=11 for semi-circle one.
Then we are to find the diameter of the second semi-circle. Given the entire length to be 30 feet, 30-22 leaves us with 8 feet as its diameter thus r=4.
Left: r=11
Right: r=4
Then, plugging both into the formula for area of a circle, we get
Left: 380.1327
Right: 50.26548
We must divide each by two because we are only looking for semi-circle which is exactly half the area of a full circle.
Then,
Left: 190.066
Right: 25.1327
190.066+ 25.1327= 215.199 = 215.2ft^2
Answer:
hi the answer would be x= -1 14/15
To find this, simply take the largest value of the set and subtract it by the smallest value of the set. In set one, you do 24-13 to get 11
In the second set, you do 95-68 to get 27
Thus, set two has a wider spread and a range of 27, with an answer choice of D

Answer:
so the number of boys is 36
Step-by-step explanation:
let the number of boys be x
by using ratio and proportion rule
5:6=30:x

by cross-multiplication
5×x=6×30
5x=180
x=36
i hope this will help you :)
Answer:

Step-by-step explanation:
<u><em>According to chord-chord theorem:</em></u>
=> 
=> 
Dividing both sides by 2
=> x = 18/2
=> x = 9
