First find the slant length using the following formula:-
Formula: (pi*radius2)+(pi*radius*slant length) = entiresurface area
So: (3.14*5.252)+(3.14*5.25*slant length) = 230.79
Dividing all terms by 3.14*5.25: 5.25+slant length = 14
Subtract 5.25 from both sides: slant length = 8.75
Use Pythagoras to find height: 8.752-5.252 = 49 and sq rt is 7
Therefore: slant length = 8.75 cm and perpendicular height = 7 cm

How do you find the volume and surface area of a parellagram?
It has no volume because it's a 2D shape but its surface area is:- length*perpendicular height
How do you calculate a surface area of a triangle?
Area of a triangle = 0.5 times base times perpendicular height
Find the surface area of a cylinder with a radius of 13 and a height of 7.?
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
How do you find the surface area of cylinder when you have the base and height?
Entire surface area = (2piradius2)+(pidiameterheight) in square units
What is the lateral are of a right cone if the base is 6 and the height is 14?
Given a base radius of 6 and perpendicular height of 14, the curved surface area of the cone is 287.1 square units.
What is Ph in the formula for the surface area of a prism?

How do you find the surface area of cylinder when you have the base and height?
Entire surface area = (2piradius2)+(pidiameterheight) in square units
What is Perpendicular Height?
That means that the height should be measured perpendicular to some other line (or plane in some cases). For example, to calculate the area of a triangle, the formula is (1/2) x base x height, where the height must be measured perpendicular to the base.
What do you do to calculate the front surface of a box?
Because a box has 6 faces, the "front surface" is not detailed enough. If you are referring to the surface perpendicular to the ground and is facing you, then you simply multiply the height of the box by the edge of the base on the front surface.
What is the definition of perpendicular height?
Height from top to bottom.
