Answer:
<h2>351. 86 yd² </h2>
Step-by-step explanation:
As = 2πrh + 2πr²
where r = 4, h = 10
plugin values into the equation:
As = 2π (4) 10 + 2 π (4)²
As = 251.33 + 100.53
As = 351. 86 yd²

Graph is below
97.15 is the area. All I did is multiply both numbers.
1. $25.02
2. $13.75
I’m not sure about the last two, sorry!
Answers:
y = 50
angle AOB = 100
=========================================
Explanation:
Angle x is an inscribed angle that subtends or cuts off minor arc AB. This is the shortest distance from A to B along the circle's edge.
Angle y is also an inscribed angle that cuts off the same minor arc AB. Therefore, it is the same measure as angle x. We can drag point D anywhere you want, and angle y will still be an inscribed angle and still be the same measure as x.
-------------------
Point O is the center of the circle. This is because "circle O" is named by its center point.
Angle AOB is considered a central angle as its vertex point is the center of the circle.
Because AOB cuts off minor arc AB, and it's a central angle, it must be twice that of the inscribed angle that cuts off the same arc.
This is the inscribed angle theorem.
Using this theorem, we can say the following
central angle = 2*(inscribed angle)
angle AOB = 2*(angle x)
angle AOB = 2*50
angle AOB = 100 degrees
