Answer:
Solution given:
diameter=14cm
radius [r]=14/2=7cm
now
area of semi circle or shaded region: ½πr²=½(3.14*7²)=76.93cm²[approximately]
22/100:
You can actually divided the numerator and denominator by a number that can go into both 22 and 100 but also not get a remainder.
So 22/2= 11
And 100/2=50
Combined you get 11/50
Hope it helps!!!
The answer is D i’m pretty sure but i’d get that checked out again
Answer:
r=244745.8 (approximately)
Step-by-step explanation:
r=x²/y
ry-x²=0
r(59000)-(380000)²=0
r=380000²/59000
r=144400000/59
r=244745.8 (approximately)
To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.
c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
