Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m
Answer:
see below
Step-by-step explanation:
7 x 13 (split 13 into 10 + 3)
= 7 x ( 10 + 3) (expand parentheses by distributive property)
= (7 x 10) + (7 x 3)
= 70 + 21
= 91
70,000 * (1+.022/12)^(12*20)
70,000 * (1.552081849 = 108,645.73
108,645.73 - 70,000 = $38,645.73 in interest in 20 years
