Answer:
A = 113.1 in^2
Step-by-step explanation:
The diameter is 12 inches
The radius is d/2 = 12/2 = 6 inches
The area of a circle is
A = pi r^2
Assuming pi is used by the pi button on the calculator
A = pi * 6^2
A =113.097335
Rounding to the nearest tenth
A = 113.1
Answer:
7.848
Step-by-step explanation:
- Multiply the 6 and 8 to get 48
Since 48 is greater than 9, you'll have to carry the 4
- Multiply the 3 and 8 to get 24.
- And, add the carried 4 to get 28.
- Since 28 is greater than 9, you'll have to carry the 2.
Answer:
x = 128°
Step-by-step explanation:
123 + 109 + x = 360
x = 360 - (123 + 109)
x = 360 - 232
x = 128°
3(x - 4) + 8(x + 2)
3*x - 3*4 + 8*x + 8*2
3x - 12 + 8x + 16
3x + 8x - 12 + 16
11x + 16 - 12
11x + 4
