Need help asap The answer is 100 or 126

Serga [27]

Answer:

The surface area of the cone is 126π cm².

Step-by-step explanation:

The surface area of a cone can be found using this formula:

$\text{SA} = \pi r ^2+\pi r l$
where r = radius and l = slant height

In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.

Substitute these values into the formula for the surface area of a cone.

$\text{SA}= \pi (9)^2+ \pi(9)(5)\\$
$\text{SA}= \pi (81)+ \pi(45)$
$\text{SA}= 126 \pi$

The surface area of the right cone is 126 π cm².

Someone please help me with this question! How can I prove it?

Alex73 [517]

Answer:

TS=QV

Step-by-step explanation:

To prove SAS congruence, you need to prove that two lines and the angle between them are all respectively equal.

In the diagrams we already have RS=WV and ∠RST=∠WVQ, so it follows that we need to prove that TS=QV.
