given figure is a solid made up of a cone and hemisphere. the total height of figure is 20cm and slant height of cone is √218 cm. if the centimetres measure of the radius of the base is a multiple of 7 find the volume​

Solve for x and select the correct answer

Graph the line with the given slope m and y-intercept b. m=-3,b=1

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
