Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
Multiply 7 and 8 which is 56
To go from kilometers to miles we have to divide 60 by 1.6 to get 37.5 miles. Now we need to divide 37.5 by 70 to get approximately 0.5. The answer is B. 0.5
Answer:
b
Step-by-step explanation:
R and s are parallel
m<2 = m<6
but m<6 + m<8 = 180
so
m<2 + m<8= 180
answer
B. m<2 + m<8= 180
