Answer:

154π cm²

Step-by-step explanation:

Radius (r) = 7 cm

Height (h) = 4 cm

Surface area of cylinder

= 2πr (h + r)

= 2π (7) (4 + 7)

= 2π (7) (11)

= 2π (77)

= 154π cm²

Answer:

154π cm²

Step-by-step explanation:

Formula for the Surface Area of a Cylinder

SA = 2πr (h + r)

Solving

Here r = 7 cm and h = 4 cm
SA = 2πr (h + r)
SA = 2π × 7 (7 + 4)
SA = 14π × 11
SA = 154π cm²

Which is the graph of f(x)=2(3)^x

likoan [24]

Let's plug the values and see which couple satisfy the equation: since $y = 2\cdot 3^x$ , if we plug the values from the first option $(x,y)=(1,6)$ we have

$6 = 2\cdot 3^1 = 2\cdot 3$

which is correct.

If we plug the values from the second option $(x,y)=(1,9)$ we have

$9 = 2\cdot 3^1 = 2\cdot 3$

which is not correct

If we plug the values from the third option $(x,y)=(2,9)$ we have

$9 = 2\cdot 3^2= 2\cdot 9$

which is not correct

If we plug the values from the fourth option $(x,y)=(2,12)$ we have

$12 = 2\cdot 3^2= 2\cdot 9$

which is not correct

So, the answer is the first one.

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint. How many pints of yellow paint will be needed i

katrin2010 [14]

Answer:

$1\frac{7}{8}$

Step-by-step explanation:

Given:

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint.

Question asked:

How many pints of yellow paint will be needed if the mixture contains one pint of blue paint ?

Solution:

We will easily find quantity of yellow paint, will be needed in the mixture, contains one pint of blue paint by using unitary method:

By using $\frac{2}{5} \ pint$ blue paint, yellow paint requires = $\frac{3}{4} \ pint$

By using 1 pint blue paint, yellow paint requires = $\frac{3}{4} \div\frac{2}{5} \\$

$=\frac{3}{4} \times\frac{5}{2} \\\\ =\frac{15}{8} \\\\ =1\frac{7}{8} \ pint$

Thus, $1\frac{7}{8}$ pint yellow paint requires in the mixture with one pint of blue paint.
