What do you mean by the radius of 4? Radius is used in circles. Do you mean that the breadth is 4?
If so you can use Pythagoras's Theorem to find the 'slant height' (provided that it is a right-angle triangle)

How do you find the slant height of a pyramid with a rectangular base?
If you make a line from the top of the pyramid to the center of the base, you have the height of the pyramid. This meets at the midsegment of a line going across the base. Since the height of a pyramid is perpendicular with the base, get this: the height, a line of 1/2 the length of the base, and the slant height form a right triangle. So, you can use the Pythagorean Theorem! For example, if the base length is 6 and the height of the pyramid is 4, then you can plug them into the Pythagorean Theorem (a squared + b squared = c squared, a and b being the legs of a right triangle and c being the hypotenuse). 1/2 the length of the base would be 6 divided by 2=3. 3 squared + 4 squared = slant height squared. 9+16=slant height squared. 25= slant height squared. Slant height=5 units. You're welcome!
If a triangle has an area of 16 and a base of 4 what is the height of the triangle?
area of triangle =(1/2)(base)(height) 16=(1/2)(4)h h=8
Given radius and chord length. What is the height of arc to midpoint of chord?
Draw the circle O, and the chord AB. From the center, draw the radius OC which passes though the midpoint, D, of AB. Since the radius OC bisects the chord AB, it is perpendicular to AB. So that CD is the required height, whose length equals to the difference of the length of the radius OC and the length of its part OD. Draw the radius OA and OB. So that OD is the median and the height of the isosceles triangle AOB, whose length equals to √(r2 - AB2/4) (by the Pythagorean theorem). Thus, the length of CD equals to r - √(r2 - AB2/4).
The base of a triangle is equal to 4 what is the height of the triangle if the area is 28?
If the base of a triangle is b and the height of the triangle is h, the area of the triangle is given by the formula: area = 0.5 x b x h.As such, in your case we have 28 = 0.5 x 4 x h, which means that h = 14.

What is the surface area of a cone whose base radius is 4CM and has a slant height of 6CM?
Surface area = pi*4*6 = 75.398 square cm
What is the slant height of a pyramid that has all sides as equilateral triangles with sides of length of 9 cm and the surface area of the pyramid is 140.4 square cm?
The surface area of the pyramid is superfluous to calculating the slant height as the slant height is the height of the triangular side of the pyramid which can be worked out using Pythagoras on the side lengths of the equilateral triangle: side² = height² + (½side)² → height² = side² - ¼side² → height² = (1 - ¼)side² → height² = ¾side² → height = (√3)/2 side → slant height = (√3)/2 × 9cm = 4.5 × √3 cm ≈ 7.8 cm. ---------------------------- However, the surface area can be used as a check: 140.4 cm² ÷ (½ × 9 cm × 7.8 cm) = 140.4 cm² ÷ 35.1 cm² = 4 So the pyramid comprises 4 equilateral triangles - one for the base and 3 for the sides; it is a tetrahedron.

What is the lateral area of a right circular cone if the diameter of the base is 4 meters and the slant height of the cone is 15 m?
First is to understand the terms. Lateral area is the surface area of a 3D figure, excluding the area of any base. Laterial Area (L.A.) of a right cone = pi*radius*slant height radius = 1/2 * diameter L.A. = pi*(1/2)*(4)*(15)=30*pi the formula for this is pi*r*rt(r^2 + h^2). If the diameter is 4, then the radius is 2. If the slant height is 15, then to get the real height we use the Pythagorean Theorem and get rt(221). So the lateral area is pi*2*rt(2^2 + (rt221)^2)...= 2pi*rt(225) = 30pi = 94.248 meters squared which is rounded to 94 meters squared.

What is the area of a Reuleaux triangle that has a diameter of 4 in?
its 1/2 the area of a circle with the length of on side of the triangle as the radius. then subtract 2 times the area of said equilateral triangle. (to find its height, use the Pythagorean theory. split the triangle in half to get its height, the base will be 1/2 the length of its side. Type your answer here...
