Answer:
5,089.4 cm³
Step-by-step explanation:
Volume of the cylinder = πr²h
Where,
r = 9 cm
h = 20 cm
Volume of cylinder = π×9²×20 = π×81×20
Volume = 5,089.3801 ≈ 5,089.4 cm³ (1 dp)
Answer:
Step-by-step explanation:
Lupita brought seven pounds of pretzels at a local wholesaler for 16.80. This means that the rate at which she bought one pound of pretzel at the local wholesaler would be
16.80 / 7 = $2.4 per pounds of pretzels
Her friend, Charles about 5 pounds of pretzels at the supermarket 12.75. This means that the rate at which Charles bought one pound of pretzel at the supermarket would be
12.75 / 5 = $2.55 per pounds of pretzels
Charles's reasoning is wrong because the rate at which he bought one pound of pretzel is higher than that of Lupita's
X=2
So,
=4^2×2 -100
=4^4-100
=256-100
=56
Answer:
d = 167.7 m
Step-by-step explanation:
We have,
Mrs. Tyner drove about 150 km east from Pearland, to Houston, Texas. She drove about another 75 km north to Dallas.
It is required to find the approximate air distance from Pearland to Dallas, Texas.
The resultant vector will give the approximate air distance. So,
So, the approximate air distance from Pearland to Dallas, Texas is 167.7 m.
