Find the surface area and volume of a cylinder with a diameter equal

dangina [55]

Answer:

Volume = 1539.38 cm³

Surface Area = 747.7 cm²

Step-by-step explanation:

Volume = πr² h

V = π(7)²(10)

V = π(49)(10)

V = 490π

V = 1539.38 cm³

Surface Area = 2πrh + 2πr²

SA = 2π(7)(10) + 2π(7)²

SA = 2π(70) + 2π(49)

SA = 140π + 98π

SA = 238π

SA = 747.7 cm²

Cristina bought a bag of coffee for $8.47. The weight of the bag was 7/8 of a pound. What was the price, per pound, of the coffe

SpyIntel [72]

~For this problem, you need to divide.
~The easy way that I think might help you is if you change the fraction into a decimal.

$\frac{7}{8} = 0.875$

Now divide $8.47 by 0.875
$\frac{8.47}{0.875} = 9.68$

The price per pound of the coffee was $9.68
