What’s the area and the perimeter and of the triangle?
asambeis [7]

Answer:

Area = 3.3998

Perimeter = 2.9

Step-by-step explanation:

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a,b,c be the lengths of the sides of a triangle. The area is given by:

Area =  √  p  ( p − a )  ( p − b )  ( p − c )    

where p is half the perimeter, or  

a + b + c / 2

 p = 1.7 + 1.7 + 2.4 / 2 = 5.8 /  2 = 2.9

a = Area = 3.3998

Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.

3 3Cylinder A 3 3 4 4Cylinder B 2 2 What is the ratio of the volume of Cylinder A to the volume of Cylinder B? Choose 1 answer:
frutty [35]

Answer:

(D)  \dfrac{27}{16}

Step-by-step explanation:

Volume of a Cylinder =\pi r^2h

<u>Cylinder A</u>

Height = 3 Units

Radius = 3 Units

Volume =\pi \times 3^2 \times 3 =27\pi$ cubic units

<u>Cylinder B</u>

Height = 4 Units

Radius = 2 Units

Volume =\pi \times 2^2 \times 4 =16\pi$ cubic units

\dfrac{\text{Volume of Cylinder A}}{\text{Volume of cylinder B}}=\dfrac{27\pi}{16\pi}\\\\=\dfrac{27}{16}

The correct option is D
