8 and 1 are alternate exterior angles.
Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)
The radius of the ball is 7 meters.

Step-by-step explanation:
By arc sum Postulate of a circle:
2 x + 3x + 4x = 360°
9x = 360°
x = 360°/9
x = 40°
3x = 3* 40° = 120°
By inscribed angle theorem:
By tangent secant theorem:
Since, measure of central angle is equal to the measure of its corresponding minor arc.
By angle sum Postulate of a triangle:
Answer: C. A line that rises from left to right has a positive slope.
Step-by-step explanation: A. has a slope of 0, B. has an undefined slope, and D. is supposed to go left to right not right to left.
Answer:
Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9
EX: item cost $100
$100 x 0.9 = $90
Meaning the price of the item after the discount is applied would be $90
