Answer:

A negative number that is 12 less than its square is -3.

Step-by-step explanation:

This is because (-3)² = 9 and 9 - 12 = -3.

You can get this answer by testing different number until one works in the given situation. This is done by testing numbers by squaring them and then subtracting 12 to see if it equals the original number.

$\mathcal \pink{GIVEN:}$

Radius = 3 m
Height = 7 m

$\mathcal \purple{TO \: FIND:}$

Volume = ?

$\mathcal \blue{CALCULATION:}$

$\qquad{ \sf \: volume = \pi{r}^{2}h }$

Where,

r is radius
h is height

$\qquad{ \tt\nrightarrow \: \frac{22}{7} \times {3}^{2} \times 7}$

$\qquad{ \tt\nrightarrow \: \frac{22}{ \cancel7} \times {3}^{2} \times \cancel7}$

$\qquad{ \tt\nrightarrow \: 22 \times {3}^{2} }$

$\qquad{ \tt\nrightarrow \: 22 \times 9 }$

$\qquad{ \boxed{ \tt\Rrightarrow \: 198\: {m}^{3} }}$

➪ Henceforth, The volume of the cylinder is 198 m³...

Which of the following points is no coplanar with points A,C, and D

Leni [432]

Answer:

Option A is correct.

Point T is not co-planar with points A, C and D

Step-by-step explanation:

Co-planar states that those which lies in the same plane.

Point A, C and D are lies in the Plane AEDC.

Since, this plane also contains points S and U.

Thus, point A, C , D , E, S and U are co-planar

but point T does not lie in the plane AEDC.

Therefore, point T is not co-planar with points A, C and D
