Answer:
2
Step-by-step explanation:
Because 3-1 is 2 and 1/4-1/4=0
So 2
Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
Answer:
Step-by-step explanation: This is for #6 Volume = pi·r2·h
Volume = pi·(5x+2)2(2x+8)
Answer:
literally, cant be either of them, angle A comes no where near 10 degrees
