Is This A Good Or Bad Thing?
I believe that your asking for two answers. The volume of the pyramid is 15 cubic centimeters and If the slant increases by 4 centimeters and its hheight increases by 2 centimeters the volume increases by 6 centimeters because the answer would be 21. 21-15=6. Formula to get the volume of a pyramid is V=1/3*(L*W)*H. I could be wrong.
Answer:
60°
Step-by-step explanation:
A tangent, together with a radius to the tangent point and segment OA, forms a right triangle with hypotenuse 9 and opposite side 4.5. SOH CAH TOA reminds you that the sine of an agle is the ratio of the opposite side to the hypotenuse of the right triangle.
Thus half the angle at A is the angle whose sine is 4.5/9 = 1/2. That angle is 30°, so the entire angle between the tangents at A is 2·30° = 60°.
