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.
17/20 is 85% in its simplistic form... first put 85/100 and then divide both numerator and denominator by 5.
Answer:
I think it's d
Step-by-step explanation: Because they have equal sides and length
Answer:
The measure of angle DCB = 125
Step-by-step explanation:
This is because angle ACD and angle DCB are supplementary.
Supplementary angles are two angles with a sum of 180 degrees, and we know these angles are supplementary by the fact that angle ACB = 180 degrees.
Hi, hope this helps :)
Feel free to ask me if you do not understand. I used the elimination method.
