Hello!

To find the surface area of the given cylinder, we need to use the formula of the surface area of a cylinder.

The formula for the surface area of a cylinder is SA = 2πrh + 2πr².

In this formula, r is the radius and h is the height.

In the given diagram, we see that the height is 6 meters, and the radius 9 meters. With those values, we can substitute them into our formula and solve for the surface area.

In some cases, you are given the diameter. To find the radius, you would need to divide the diameter by two.

SA = 2π(9)(6) + 2π(9)²

SA = 54(2π) + 2(81π)

SA = 108π + 162π

SA = 270π

SA ≈ 848.2 m²

Therefore, the surface area of the given cylinder is choice A, 848.2 m².

Angles θ and φ are angles in standard position such that:

BartSMP [9]

When $\theta$ terminates in quadrant III, both $\cos\theta$ and $\sin\theta$ are negative, and

$\sin^2\theta+\cos^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac{12}{13}$

When $\varphi$ terminates in quadrant II, $\cos\varphi$ is negative and $\sin\varphi$ is positive, so

$1+\tan^2\varphi=\sec^2\varphi\implies\sec\varphi=-\dfrac{17}{15}$

which gives

$\cos\varphi=\dfrac1{-\frac{17}{15}}=-\dfrac{15}{17}$

$\tan\varphi=\dfrac{\sin\varphi}{\cos\varphi}=-\dfrac8{15}\implies\sin\varphi=\dfrac8{17}$

Now,

$\sin(\theta+\varphi)=\sin\theta\cos\varphi+\cos\theta\sin\varphi=-\dfrac{21}{221}$

Peter’s dog eats 0.3 kilograms of dog food each day. How much dog food will Peter’s dog eat in 8 days?

melisa1 [442]

Peter dog ate 2.4 kilograms of dog food in 8 days

Solution:

Given that peters dog eats 0.3 kilograms of dog food each day

To find: amount of dog food eaten by peter dog in 8 days

From given question,

one day = 0.3 kilograms of food

Let "x" be the amount of dog food eaten by peter dog in 8 days

Then for 8 days:

amount of dog food eaten in 8 days = amount of dog food eaten in 1 day x 8

$x = 0.3 \times 8$

On multiplying we get,

x = 2.4

Thus peter dog ate 2.4 kilograms of dog food in 8 days
