What is the surface area of a pyramid with area of the base 20 slant height 7 and perimeter of the base 30?
It is 125 square units.
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.
How do you explain the formula for area of a triangle?
the area equals one half base times height. For example : you have a triangle with a base of 5cm and a height of 6cm you multiply 5 times 6 (=30) then you divide 30 by 2 because its one half of the base times height. Hope that helps :)
What is the area of triangle if the base is 10 ft and the height is 6 ft?
Remember for ANY triangle, the area is one half multiplied to the base length multiplied to the perpendicular height length . Algebraically expressed as A = 0.5bh Substituting 10 ft & 6 ft. A = 0.5 X 10ft X 6ft = A = 0.5 x 60 sq.ft. A = 30 sq.ft.,

What is the area of the cone if it has 30 ft height and 15 ft radius?
A cone with a 30ft height and a 15ft radius has a total surface area of approximately 2,287.44 square feet.
What is the answer for The surface area of a square pyramid is 85 square meters. The base length is 5 meters. What is the slant height?
So the base is 25 meters squared, that leaves 60 for the triangles. the equation for triangles is base x height x 1/2 5 times 6 is 30 divide by 2 is 15 times 4 is 60. the answer is 6

What is the average size of a cinder cone volcano?
The average size of a cinder cone volcano can vary, but they typically range in height from 100 to 1,000 feet (30 to 300 meters) and have a base diameter of around 1,000 to 3,000 feet (300 to 900 meters).
What is the total area of a cone with a volume of 2560 piand a height of 30?
It is 800*pi = 2513 square units.
List three sets of base and height measurements for triangles with areas of 30 square units?
The area of a triangle is half base times height so any triangles whose base times height is 60 units will have an area of 30 square units e.g. base = 10 units, height = 6 units; base = 5 units, height = 12 units; base = 7.5 units, height = 8 units.
What is the surface area of a pyramid with a side length of 5 feet and a slant height of 12feet?
To calculate the surface area of a pyramid with a square base, you need the area of the base and the area of the four triangular faces. The area of the base is (5 \times 5 = 25) square feet. Each triangular face has an area of (\frac{1}{2} \times \text{base} \times \text{slant height} = \frac{1}{2} \times 5 \times 12 = 30) square feet. Since there are four triangular faces, their total area is (4 \times 30 = 120) square feet. Therefore, the total surface area is (25 + 120 = 145) square feet.
