Answer:
84.14 square units, total
Step-by-step explanation:
Use the formulas for area of the figures you're interested in.
<u>Rectangle Area</u>
A = LW
<u>Circle Area</u>
A = πr^2
__
Your rectangle area will be ...
A = 5 × 14 = 70 . . . . square units
The area of a full circle with diameter 6 (radius = 6/2 = 3) will be ...
A = π × 3^2 = 9π
The area of a semicircle of that size is half that:
semicircle area = 9π/2 = 4.5π
Then the total area of the two figures is ...
70 + 4.5π ≈ 70 +14.14 = 84.14 . . . square units
Answer: 28.26
Step-by-step explanation:
What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²
You are given the diameter in these problems, so you need radius.
For the first circle (8 in one) :
8/2=4 r=4
A=3.14(4)²
A=50.24
For the second one (10 in one) :
10/2=5 r=5
A=3.14(5)²
A=78.5
To find the measure of the annulus, you subtract those numbers, getting 28.26
Answer: Bruh im not even close to learning that stuff lol
Step-by-step explanation:
Step-by-step explanation:
9. 131+106+67+x=360
237+67+x=360
304+x=360
x=56
10. 90+90+146+w=360
180+146+w=360
326+w=360
w=34
