Answer:
Volume is about 26.5 in^3
Step-by-step explanation:
The volume = 4/3 pi r^3 where r = the radius.
the radius = 1/2 diameter = 1/2 * 3.7 = 1.85 ins.
So V = 4/3 * 3.14 * 1.85^3
= 26.5084
Answer:
I think the answer is -25
Step-by-step explanation:
#27.
First cross multiply
2 (2a-3) = 3 (a-1)
next use the distribute property on both sides
4a - 6 = 3a - 3
combine like terms, subtract 3a from both sides and add 6 to both sides
a = 3
#28
cross multiply
3x = 4, then divide both sides by 3
x = 4/3
#30
add 1/4 to both sides
3/x = 1/2 + 1/4, find a common denominator for the right side fractions
3/x = 2/4 + 1/4 = 3/4
therefore, x = 4
Answer:
Answer: 155.12km
Step-by-step explanation:
sin(64˚) x 78 = 70.11 (2DP)
70.12 (2DP) + 85 = 155.1059356 (155.12 - 2DP)
Your answer will be 5xplus10
