X-y=11
2x+y=19
add them
x-y=11
<u>2x+y=19 +</u>
3x+0y=30
3x=30
divide 3
x=10
sub baack
x-y=11
10-y=11
minus 10
-y=1
times -1
y=-1
(x,y)
(10,-1)
To find the volume of a sphere, you will use the formula for finding volume of a sphere. You will use the diameter to find the radius. r = d/2, so the radius is 5 in
V = 4/3 x pi x r^3
4/3 x 3.14 x 5^3
V = 523.6 cubic inches
The volume of this sphere is approximately 523.6 cubic inches.
Answer:
the answer is 9^8
Step-by-step explanation:
9^3 * 9^5 = 9^ 3 + 5 = 9^8
Its 37 and yea its an easy question lol
