Answer: 
Step-by-step explanation:
Given
The radius of the hemisphere is 
The volume of a hemisphere is given by

Insert the value

Perimeter=(2*length)+(2*width)
length=2*w
132=(2(2w))+(2w)
132=(4w)+(2w)
132=6w
w=22
l=44
40. 24+26=50 41. I don't understand that one either what grade are you in?
7y-3°=3y+13°
7y-3y= 13°+3°
4y= 16°
y=4°
Substitute y
7(4)-3°= 25°
3(4)+13=25°
180°-25°-25°=130°
2(2x+3)°+130°=180°
4x+136°=180°
4x=44°
x=11°
4t + 75 => 475, t = 100
Is this what you were looking for?
