The rule of surface area for the cone is
Pi r^2+2pi L
This means
pi*7^2+ 7*pi*9=352 feet^2
Answer:
He has 7 cookies left
Step-by-step explanation:
13-6=7 7+6=13
I'm not sure if this is what you're looking for, but maybe it will help:
Isolate y for 5=3x+2y
Switch sides:
3x+2y=5
Subtract 3x from both sides:
3x+2y-3x=5-3x
Simplify:
2y=5-3x
Divide both sides by 2:
2y/2 = 5-3x/2
Simplify:
y= 5x-3/2
I hope this helped you! :)
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
Answer:
7.56 km²
Step-by-step explanation:
Given data:
Width of the fjord, w = 6.3 km
Retreated terminus of the glacier between may 2001 and June 2005, d = 7.5 km
thus, the length lost , y = 7.5 - 6.3 = 1.2 km
now, the area is given as:
A = Length × width
on substituting the values, we get
A = 1.2 × 6.3
or
A = 7.56 km²
Hence, the surface area lost by the glacier in the fjord is 7.56 km²
