Answer:
B. 66.0
Step-by-step explanation:
The formula for circumference is 2*π*r where r is the radius. MS and MR are both radii, so we can plug in 10.5 to the formula to get 2* π*10.5, which would be about 65.97, which rounds to 66.0. Hope this helps!
Answer:
1. h
2. c
Step-by-step explanation:
R(r+r^2)=(r)(r^2)
R^2+r^3=r^3
R^2=0
R=0
39
sum of 2 digit no. can be
3+9
4+8
5+7
6+6 (which cannot be the ans since interchanging the digits would give 0 difference)
so,
93-39=54
84-48=36
75-57=18
so 93 is the reversed no. and 39 is the original no.
1st on left is the greater than
2nd on left is less than
1st on right is greater than or equal to
2nd on right is less than or equal to
