This is very simple. So you use two formulas:
Rectangle: Length • Width
Semicircle: Area = 
With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.
Area of semicircle: ≈ 0.25
Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6
For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,
Round to nearest tenth: 0.9
Round to nearest hundredths: 0.85
Answer:
s = 6 inches
Step-by-step explanation:
Given:
r = 53 inches,
∠S = 6°
∠T = 58°.
Required:
Length of s
Solution:
Use Sine Rule
Thus:
<R = 180 - (58 + 6)
<R = 116°
r = 53 inches,
∠S = 6°
s = ?
Plug in the values
Multiply both sides by Sin(6)
(nearest inch)
Answer:
22 km
Step-by-step explanation:
Well if sides of the triangle are 20 km and 21 km then it has to be 22 km
Answer:
6 divided by 1/2 essentially just multiplying the number by two. 6/(1/2)=12. 6*2=12. In this problem, you are simply dividing the number six by a part of a number, in this case one half of one. Hope that helps, let me know if not!
