Answer:
1 16/25
Step-by-step explanation:
1 whole and remaining decimal 0.64
0.64 is 64/100 as a fraction which simplifies to 16/25
So as a whole number its 1 + 16/25 which is 1 16/25
Hope this helps.
Hey there!
Formula: πr^2
r = radius
pi = 3.1415926535898 (but we can say it approximately equals 3.14)
Your equation (3.14)(4.2)^2 = answer
4.2^2 = 4.2 × 4.2 = 17.64
New equation: 17.64 × 3.14 = 55.3896
We round our answer to the nearest tenth
Answer: 55.4 ☑️
Good luck on your assignment and enjoy your day!

Answer:
arc AB = 70°
arc BC = 110°
arc ABC = 180°
arc CDB = 250°
Step-by-step explanation:
Since these angles are not inscribed, but are at the center point of the circle, the angles and arcs will be the same measure.
Solve for arc AB:
Angle AFB = 70°, so arc AB = 70°
Solve for arc BC:
Angle AFC is a straight angle so it is 180°. To find angle BFC, subtract angle AFB from 180°.
180 - 70 = 110°
Since angle BFC = 110°, arc BC = 110°
Solve for arc ABC:
Add arc AB and arc BC together.
70° + 110° = 180°
arc ABC = 180°
Solve for arc CDB:
There are 360° in a cirlce. To find arc CDB, subtract arc BC from 360°.
360° - 110° = 250°
arc CDB = 250°
The standard form would be y = 7x^2 - 42x + 67
Answer:
135°
Step-by-step explanation:
∠AOB = ∠COB = 90°
∠BOK = 45°
90 + 45 = 135°
