J L N M If mZJKN = 28º and mZKLM = 103°, find mZJML.

Bingel [31]

Answer:

98°

Step-by-step explanation:

each half adds up to 180° so 103+28=131 then 180-131=49

and that would be just one of the bottom angles so you would double it to get 98

the right rectangular prism will be sliced perpendicular to its base along the dashed line. Select from the drop-down menus to c

Tju [1.3M]

The cross section (slice) would be a rectangle.

A rectangular prism is the shape of a box with 6 rectangular sides. If you slice down perpendicular to the base, you would still have another rectangle.

A can of beans has surface area 337 cm2. It's heights is 11cm. What is the radius of the circular top?

Karolina [17]

Answer:

3.66 cm

Step-by-step explanation:

r = Radius of cylinder

h = Height of the cylinder = 11 cm

A = Total surface area of the cylinder = $337\ \text{cm}^2$

Total surface area of a cylinder is given by

$A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65$

So, the radius of the circular top is 3.66 cm.
