So,
The diameter is 8.6ft. We need to convert to radius.
2 radius = 1 diameter
8.6/2 = 4.3 ft.
3.14(18.49)
58.0586ft.²
Divide by 2 (semi-circle)
29.0293ft.²
Answer:
In triangle EFG,
EG = 4.8 units
Since angle FDE = angle FED,
EF = FD = 3.5 units [sides opposite to equal angles]
FG = DE = 3 units [Given]
s = (a+b+c)/2
= (EG+EF+GF)/2
= (4.8+3.5+3)/2
= 11.3/2
now using Heron's formula,
area of EFG =
Step-by-step explanation:
Answer:
1) 420mm
2) 837grams
3) 0.89litres
4) 0.072
5) 0.00267
Step-by-step explanation:
1) divide by 10
2) multiply by 1000
3) divide by 1000
4) divide by 1000
5) divide by 10,000
Area(S) = y×h
h = 10, area(S) = 160 mi²
160 = y×10
y = 16 mi
Answer: y = 16 mi
Answer:
Area of the rectangle A = 32 x - 8
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the length of the rectangle(l) = 8x-2
Given that the width of the rectangle (w) = 4
Area of the rectangle = length × width
A = (8x - 2) × 4
A = 32 x - 8
<u><em>Final answer</em></u>:-
Area of the rectangle A = 32 x - 8
