Answer:
1170cm
Step-by-step explanation:
52×45=2340
2340÷2=1170
The different one is C, pi times the radius
"Different" value is 18.85 and the "same" value is 37.70.
The distance around a circle, circumference and pi times the diameter all finds the same value, but pi time the radius is only half of those values
The answer is -20.
(8 × 5) - (-6 × -10)
= 40 - 60
= -20
