Answer:
145,7
Step-by-step explanation:
The area of the circle is 2πr
The area of the rectangle is b·h
Applied to this figure is:
2·π·r = 2·3,14·5 = 31,4 this is a semicircle so you have to divide by 2. 31,4/2 = 15,7
b·h = 13·10 = 130 (you can know the high because the double of the radio is the diameter)
130 + 15,7 = 145,7
103.8 units^2
rectangle:
13*5=65
semi-circle:
5*5*3.1=77.5
77.5/2=38.75
38.75+65=103.75 units^2
round to 103.8
Im pretty sure you use addition? I may be wrong
Nearest whole is 4
36
Hope it helps...
Have a great day :P
I think it's 5 to the power of 8
Just put (5^4)2 in the calculator to get 390,625. Then put 5^8 in the calculator to get the same number 390,625.
