When A right cone has a slant height of 7 and a radius of 5 what is the surface area?
The surface area consists of the circular base and the sloped side. By cutting the sloped side from the apex to the base, it can be "flatten" out into a sector of a circle - the length of the arc is the same as the circumference of the base, and it is a fraction of the whole circle with radius of the slant height, which can be applied to the area of the circle. → surface area = area case + area sloped side = π × 5² + (π × 7²) × (2 × π × 5)/(2 × π × 7) = 25π + 49π × 5/7 = 25π + 35π = 60π square units ≈ 188.5 square units
What is the surface area of 5x7x6?
I'm assuming that your figure is a rectangular prism. Here are the calculations to find the surface area:5*7*2=705*6*2=607*6*2=8470+60+84=214 un2
What is the are of a 5 inch by 7 inch photograph?
Is the question What is the AREA of a 5 inch by 7 inch photograph? The area of the photograph is 5 x 7 = 35 square inches. But if you are asking how much surface area does a 5 inch by 7 inch photograph have, you have to consider the area of both the front and the back of the photograph or 70 square inches.
The curved surface area of a right circlur cylinder of height 14cm is 88 cm find the diameter of the base of the cylinder?
The surface area of a cylinder = height * 2 * pi * radius So, since we know the surface area, and the height, we can rearrange the equation: radius = Surface Area / (height * 2 * pi) = 88/(14 * 2 * pi) = 22/ (7*pi) = approx 1 cm. So the diameter, is 44/ (7*pi) = approx 2 cm.
What is the surface area of a cylinder with a radius of 7cm and a height of 25cm?
The formula in getting the surface area of a cylinder is 2 pi r2 + 2 pi r hSAC = (2)(3.14)(7)2 + (2)(3.14)(7)(25)= (2)(3.14)(49) + (2)(3.14)(7)(25)= (6.28)(49) + (6.28)(175)= 307.72 + 1099SAC = 1406.72 cm3
