Ashton bought 5 cans of olive oil. Each can had a radius of 3.2 inches and was 15 inches tall. Find the total cubic inches of ol

amid [387]

Step-by-step explanation:

A can is a cylinder.

Volume of a can = Volume of Cylinder

$= \pi {r}^{2} h$

Given Radius = 3.2 inches and height = 15 inches,

Volume of one olive oil can =

$\pi( {3.2}^{2} )(15) \\ = 153.6\pi {in}^{3}$

Volume of 5 olive oil cans = 5 x volume of one olive can

$= 5 \times 153.6\pi \\ = 768\pi {in}^{3}$

I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.

Peter has $100. The price of a watch is $60. If peter gets 25% discounts, can he buy 2 watches

slamgirl [31]

Do 60 divided by 4 ( 25 percent) which is 15. 60-15 is 45. 45 plus 45 is 90 so yes he has enough money to buy two watches

A 20 ft. ladder is used against a 15 ft. wall. What is the measure of the angle made by the ladder and the ground (nearest whole

Brrunno [24]

Step-by-step explanation:

Given that,

The length of a ladder, H = 20 feet

The height of the wall, h = 15 ft

We know that,

$\sin\theta=\dfrac{h}{H}$

h is perpendicular and H is hypotenuse

So,

$\sin\theta=\dfrac{15}{20}\\\\\theta=\sin^{-1}(\dfrac{15}{20})\\\\\theta=48.59^{\circ}$

Now using Pythagoras theoerm,

$b=\sqrt{H^2-h^2}\\\\b=\sqrt{20^2-15^2}\\\\b=13.2\ ft$

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
