The surface area of a sphere is π x 4 x radius²
so let the radius be r
π x 4 x r² = 2122.64
r = 13 inches
This is a tough one especially for me. I'll find out. Did you get the answer yet though?
Answer:
x= 28°
Step-by-step explanation:
180-118=62
62+90=152
180-152=28
BAM x=28°
The circle is open if the inequality is greater than (>) or less than (<) and closed if the inequality is greater than or equal to (≥) or less than or equal to (≤)
If the arrow points to the right (—>) towards bigger numbers, x (whatever number is on the line) will be GREATER (> or ≥)
If the arrow o points to the left (<—) towards smaller numbers, x will be LESSER (< or ≤)
1. Starts at -2 with a closed circle and goes in the positive direction —>
So x ≥ -2
2. Starts at 2 with an open circle and goes in the negative direction <—
So x<2
And the rest use the same method.
Answer
8 is not greater than 10
Step-by-step explanation:
2x>10
2(4)>10
8<10
x=4 can not be the solution to this equation because 8 is less than 10
*just as a side note think of the > sign as an alligator, the mouth always is open towards the larger number
