The area of triangle is : 18.0
15 square cm
Area = 0.5*3*2.8 = 4.2 square cm
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
Half the base times the height = 15cm2
The area of triangle is : 18.0

15 square cm
What is the area of a triangle with base 2cm and height 3cm
Area = 0.5*3*2.8 = 4.2 square cm
The area is 12cm2
yes. take an obtuse triangle that has a base of 8cm and a height of 3cm. then, take a right triangle that has a base of 3 cm and a height of 4 cm. do the math. the obtuse triangle will have a greater area. hope this helps.
The information given is a classic example of the dimensions of a right angled triangle with a hypotenuse of 5cm, a base of 3cm and a height of 4cm. Area of a triangle = 1/2*base*height Area = 1/2*3*4 = 6 square centimetres
Area of trapezoid: 0.5*(5+3)*3 = 12 square cm
surface area? b/c that's the area of a 3-d object. But there is also volume. SA=find the area of each face and add them together(1/2 base times height for triangles and B times H for rectangels) V= the area of the base times the height 8cm 6cm 7cm 3cm
3 x 5 ie 15 cm2
