Answer: 36π
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
because area of sphere equals =
so if we doubled the radius the surface area will be doubled

okay so first add help the subtract help help finally dividing the help^2 equally help/help
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
32. The absolute value of a number x (|x|) will always be positive. It just means how far the number is from 0 on the number line.
