If AB CD and AC≅BD, what theorem can be used to show that △ACD≅△CAB

If two sides of a triangle are congruent, the angles opposite these sides are ... CD bisects AB. CD ⊥ AB. 2. AD ≅ DB Side. 3. ∠CDA and ∠CDB are right ∠. 4. ... AB ≅ CD. Prove: EC ≅ FB. Statement. 1. ∠A and ∠D are a rt ∠. AE ≅ DF Side ... 3. ∠DAB ≅ ∠CBA Angle. 4. AB ≅ AB Side. 5. ΔDAB ≅ ΔCBA. 6. AC ≅ BD.

Step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
