Answer:
Volume=1232cm Surface area=660cm
Step-by-step explanation:
Volume=π x r² x t
=22/7 x 7 x 7 x 8
=1232cm
Surface area=2 x π x r x (r+t)
=2 x 22/7 x 7 x (7+8)
=44 x 15
=660cm
SORRY IF I AM WRONG, I'M TRYING MY BEST
Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²

Answer:
(b) ∠EGF ≅ ∠BDC
Step-by-step explanation:
Angles D and G are both marked with double arcs, indicating they are congruent:
∠EGF ≅ ∠BDC
__
<em>Other choices</em>:
BD is the short segment between the marked angles. It has no "decoration." EF is the longer segment with a single hash mark decoration. These are not corresponding parts, so are <em>not congruent</em>. There is no right angle in these triangles, so the <em>Pythagorean theorem is not applicable</em>.
__
CD is the longest side, with no decoration. EF is the middle-length side with a single hash mark decoration. These are <em>not corresponding sides</em>.
