Answer:
S = 3.92π
Step-by-step explanation:
The formula for area of a sector is
S = (Ф/360°)πr² where Ф is the angle of the sector in degrees, and r is the radius.
The radius is half of the diameter, so we have 5 = 5.6/2 = 2.8, and Ф = 180°
The area is
S = (180°/360°)π(2.8)²
S = (1/2)π(7.84)
S = 3.92π
Answer:
Step-by-step explanation:
(0,-20)
1.8903
because if you do the math its easy
The answer is 7 outside the square root. Another 7 will be inside the square root. Then over 8
Answer:
4.50+1.25n=8
Step-by-step explanation:
subtract 4.50 from both sides of the equation which would leave 1.25n=10
then divide 1.25 from 1.25n and 10
n=8
I hope this helps you! i want brainliest sooo bad lol!
