Answer:
236.715 ft²
Step-by-step explanation:
The figure consists of the rectangle with sides 15 ft and 4 ft and two semicircles with diameter 15 ft (radius 7.5 ft).
The area of the rectangle is
A₁=15·4=60 ft²
The area of two semicircles together is the area of circle. Thus,
A₂=πr²=π·7.5²=56.25π≈176.715 ft²
The area of the figure is
A=A₁+A₂=60+176.715=236.715 ft²
Angle = 68⁰ is an inscribed angles, this angle equal 68⁰,
so it intersect arc = 2*68⁰= 136⁰.
Arc of the whole circle (circumference) =360⁰,and it also =b+104+136.
b+104+136 =360
b=360-(104+136) = 120⁰
Answer A. b=120⁰.
Answer:
Step-by-step explanation:-12x=2
X=-12/2
X=-6
A mixed number is an integer--whole number--in front of a fraction. To calculate this, you have to divide the numerator by the denominator and put the remainder over the denominator.
Since 3 goes into 16 wholly 5 <em />times with 1 left over, 16/3 = 5 1/3.
