Answer:
818.4 ft^2 to the nearest tenth.
Step-by-step explanation:
The area of the shaded segment = the area of the sector - area of the triangle
= (150/360) * π * 27.8^2 - 0.5 * 27.8^2 * sin 150
= 818.4 ft^2.
Answer:
C, C and A
Step-by-step explanation:
using the formulae relating to the circle
• Area (A) = πr² ( r is the radius )
• Circumference (C) = 2πr ( r is the radius )
(8)
Area of the interior with r = 4
A = π × 4² = 16π ≈ 50.27 ft² → C
(9)
Area of exterior with r = 7
A = π × 7² = 49π ≈ 154 ft² → C
(1)
Circumference of exterior circle with r = 7
C = 2 × π × 7 = 14π ≈ 44 ft → A
Answer:
3:2
Step-by-step explanation:
45, 30
both divisible by 15, so:
3 : 2
bc :
3*15 = 45
2*15 = 30

Answer:
x < 6.
Step-by-step explanation:
18 > 12+x
18 - 12 > x
x < 6.
The graph will be a vertical dotted line passing through the point (6, 0) and shaded to the left.
