B using more coal to make electricity
Answer:
176.625 sq.ft, 4.8 sq.ft
Step-by-step explanation:
Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.
Answer:
x^2 14x + 49
Step-by-step explanation:
Use F.O.I.L method
FIRST: x * x = x^2
OUTSIDE: 7*x
INSIDE: 7*x
LAST: 7*7= 49
x^2 + 7x + 7x + 49
x^2 14x + 49
First of all is it am or pm
am is 0530 hours
pm is 1730 hours
