10 +100 ÷ (15+5) +4²
Ainat [17]

Answer:

31

Step-by-step explanation:

Using PEMDAS we know that you start with parenthesis, which would give us twenty within the brackets. Then you would solve for the exponent, which would give you sixteen but you do not add the exponent to the parenthesis until you divide. 100 divided by 20 is five, then you add ten and sixteen, giving you 31.

What is the volume of the cylinder below? Use 3.14 for pi and I round to the nearest tenth
Rainbow [258]

Answer:

Option (4).

Step-by-step explanation:

Formula to calculate the volume of a cylinder is,

V = πr²h

Here r = radius of the cylinder

h = Height of the cylinder

From the figure attached,

r = \frac{13}{2}=6.5 cm

h = 11 cm

Now we substitute the values of h and r in the formula,

V = π(6.5)²(11)

   = 464.75π

   = 1459.32

   ≈ 1459.3 cm³

Therefore, volume of the given cylinder is 1459.3 cm³

Option (4) will be the answer.

tamaranim1 [39]

Answer:

-8.05

Step-by-step explanation:

In order to solve for C you first have to subtract 17.6 from both sides.

2c=(6/4)-17.6

6/4 is 1.5

1.5-17.6=-16.1

2c=-16.1

c=-8.05
