Answer:
A = 50.24 cm
Step-by-step explanation:
Area formula of a circle:
A = π r²
diameter- r+r
which means that your diameter(8) divided by 2 = 4
r of circle= 4
A= 3.14(4²)
A = 3.14(16)
A = 50.24 cm
What I’m support to fine it in the graph or find the slop, solve for x or y???? Put the whole question so I can help you
Answer:
70°
Step-by-step explanation:
Connect the center of the circle with endpoints of the chord. Let the center of the circle be point O and endpoints of the chord be points A (let point A lie on the tangent line too)and B.
From the figure, central angle AOB has the measure of 220°.
Consider triangle AOB. This triangle is isosceles triangle because OA and OB are both radii. In this triangle the measure of angle AOB is 360° - 220° = 140°.
Angles OAB and OBA are angles adjacent to the base AB, so they are congruent. The sum of the measures of all interior angles in triangle is always 180°, so
m∠OAB + m∠OBA + m∠AOB = 180°
m∠OAB = m∠OBA = 1/2 (180° - 140°)
m∠OAB = 20°
Since drawn line is tangent line, then OA is perpendicular to this tangent line and
x° = 90° - 20°
x° = 70°
