The side of a triangle measured 7cm,8cm ,12cm . which type of triangle is it

Obtuse triangle.

Step-by-step explanation:

The rule to know what type of triangle it is, you do A^2 + B^2 and if it is less than C^2, then it is obtuse. If it is equal, then it is right, and if it is more than, it is acute.

Do this equation fo 7, 8, and 12

7^2 + 8^2 =? 12^2

49 + 64 =? 144

113 < 144

113 is less than 144 which means that it is an obtuse triangle

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

don't report but were is the digram
