Answer:
8. C=131.88 mm
9. C=40.82 ft
10. A=254.34 in²
Step-by-step explanation:
8. diameter of 42 millimeters- circumference?
Radius is half of 42, so 21 mm
Circumference=2πr
C=2π21
C=131.88 mm
9. diameter of 13 ft- circumference?
radius is half of 13, so 6.5
Circumference=2πr
C=2π6.5
C=40.82 ft
10. radius of 9 in- area?
Area=πr²
A=π9²
A=π81
A=254.34 in²
Answer:
$4
Step-by-step explanation:
Because he bought 5 smoothies and they were each $20, you have to do 20÷5. Then you get $4 as your answer.
Answer:
I only have an answer to number 2 but the dimensions are 20 and 120.
Step-by-step explanation:
well you can remove the zeroes and factor either the 28 or 24. (I think 24 is the best) so when you factor it you get 2 and 12 because 2 x 12 is 24 and 2 + 2 + 12 + 12 is 28. Then add the zeroes and you have your dimensions. I hope that explanation helped with number 2.
Answer:
70 degrees
Step-by-step explanation:
Angle HMK = 50 degrees
Angles LMK, MLK and MKL are equal to 60 degrees, being in a perfectly congruent triangle which they all add up to 180 degrees.
Add 60 to 50 = 110
180 - 110 = 70 degrees, equal to angle HMG.
This is because the line that angles LMK, HMK and HMG are on is supplementary.
