The surface area of sphere is 616
WebAug 25, 2024 · Step 1: Note the radius of the given sphere. Here, the radius of the sphere is 47 cm. Step 2: We know that the surface area of a sphere = 4πr 2. So, substitute the value of the given radius in the equation = 4 × (3.14) × (7) 2 = 616 cm 2. Step 3: Hence, the surface area of the sphere is 616 square cm. WebIn fact, if we melt a single large sphere into a number of smaller ones, the combined volumes of the smaller ones match the size of the large spherical. Given surface area of the sphere = 616 cm 2. 4π R 2 = 616. 4×(22/7)R 2 = 616. R 2 = 616×7/4×22. R 2 = 49. R = 7. Volume of the solid metallic sphere = (4/3)π R 3 = (4/3)π x 7 3 = (1372/3 ...

WebCorrect Answer: Option C Explanation. Surface area of a sphere = \(4\pi r^2\) = \(4 \times \frac{22}{7} \times 7 \times 7\) = \(616 cm^2\) WebThe formula for the volume of a cylinder is: V = Π x r^2 x h. "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both …
WebMar 11, 2024 · Using Standard Formula. 1) We are calculating the total surface area of sphere using the standard formula is area= (4*22*r*r)/ (7). 2) Read the radius value using scanner object sc.nextDouble () and store it in the variable r.Substitute the value in the formula and print the area value. 1. WebAnswer (1 of 7): Surface area of a sphere= 4πr^2 4πr^2 = 616 Value of π = 22/7 or you may take 3.142 or you may use calculator depending on what how do you want to deal with the situation. I The question you are given, you may notice 616 is divisible by 22, ( 6+6–1= should be a 0 or a multipl...
WebCorrect answer: Explanation: The surface area of the larger sphere is NOT merely doubled from the smaller sphere, so we cannot double to find the answer. We can use the surface area formula to find the radius of the original sphere. r2 = 4. r = 2. Therefore the larger sphere has a radius of 2 * 2 = 4. The new surface area is then square inches. WebIn the above example, the radius of the sphere is 8 cm. If the diameter is given, divide the diameter by 2 to get the radius. Step 2: Now, surface area of sphere = 4 π r 2, so after substituting the value of r = 8, we get, surface area of sphere = 4 π r 2 = 4 × 3.14 × 8 2 = 4 × 3.14 × 64 = 803.84. Step 3:
