Step-by-step explanation:
Answer:
78
Step-by-step explanation:
if something is down by 50% it means it was cut in half, or divided by 2. Therefore, you need to find wha 39 times 2 is, and that would be 78
Answer:
2^-3 = 0.125
1/8 = 0.125
2^1/2^4 = 0.125
All of these expression are equal except 8.
Step-by-step explanation:
Answer:
Half of 3 is 1.5(new radius)
1.5^2 = 2.25
2.25 x 3.14 = 7.065
7.065 x 2 = 14.13(area of two circles)
2 x 3.14 x 1.5 = 9.42
9.42(circumference) x 4(height) = 37.68(area of lateral)
Add the given areas:
37.68 + 14.13 = 51.81 cm2 is your answer.
