Radius of the circle is the length of rectangle divided by 2 (7cm)
Area of circle: pi*r²
Pi= 22/7
(22/7)*7²
=154
Since its a half circle, divide 154 by 2 =77
Area of rectangle:14*9=126
Subtract the circle from the rectangle: 126-77=49
Answer:
6/7
Step-by-step explanation:
5/7 + 1/7
Since the denominators are the same, we just add the numerators
5+1 = 6
Then we put the numerator over the denominator
6/7
5(3)-(-3)
15- (-3)
15+3 = 18
