Here,
A sphere has 7cm radius
And it’s cut into tow half (2 hemispheres)
So, the radius of a hemisphere is also 7cm
Now,
TSA of hemisphere = 3 pie r^2
=3*22/7*7^2
=3*22/7*49
=3234/7
=462cm^2
Lastly,
The TSA of 2 hemispheres = 2* 462
=924cm^2
Hence,
The total surface area of the 2 hemisphere is 924cm^2
Answer:
(-3 , -3)
Step-by-step explanation:
A: (-1,2), B: (1,2), and C: (-1,-3) .... D: (x,y)
slope of AB = (2-2)/(1 - -1) = 0 .... parallel to x axis
x coordinate of A is 2 units left to B (-1 vs 1)
y coordinate of C is 2 units left to B so D must be 2 units left to C: -1 -2 = <u>-3</u>
DC // AB , y coordinate of D = C =<u> -3</u>
D: (-3 , -3)
Answer:
can you state what point I is?
The one-way flight is represented as 150x-100miles. If we have a round trip distance to be computed, then we need to multiply it twice such as the solution is shown below:
(150x-100)*2
300x-200
Therefore, the answer is letter "C" which is 300x-200.
