Answer:

-2 or -5

Step-by-step explanation:

(2x − 8) / (x² + 7x + 10) is an invalid expression when the denominator is 0.

x² + 7x + 10 = 0

(x + 2) (x + 5) = 0

x = -2 or -5

What is measure of angle Q

Juli2301 [7.4K]

57° is the answer

A triangle adds up to 180° , a circle adds up to 180°

T = 126 °

S = 180° - 126°

S= 54°

R = 69°

Q + S + R = 180°

69 + 54° = 123°

=180° - 123° =

Q= 57°

Find the volume of a cone with a base radius of 6 cm and a height of 10 cm write in terms of pie

Savatey [412]

Answer:

Volume of the cone is 120 π cm³

Step-by-step explanation:

Given that Base radius of cone is 6 cm and height is 10 cm and we need to find volume of the cone. Volume of cone is given by:

$\\ \: \: \dashrightarrow \: \: \: \underline{\boxed{\pmb{\sf{Volume_{(cone)} = \dfrac{1}{3} \pi r^2 h }}}} \\ \\$

On Substituting the required values, we get:

$\\ \: \: \dashrightarrow \: \: \sf \: Volume_{(cone)} = \frac{1}{3} \times \pi \times {(6)}^{2} \times 10 \\ \\ \\ \: \: \dashrightarrow \: \: \sf \: Volume_{(cone)} = \frac{1} {\cancel{3}} \times \pi \times \cancel{36} \times 10 \\ \\ \\ \: \: \dashrightarrow \: \: \sf \: Volume_{(cone)} = \pi \times 12 \times 10 \\ \\ \\ \: \: \dashrightarrow \: \: \sf \: \: { \purple{Volume_{(cone)} =120 \pi \: cm^3 }}\\ \\$

Volume of a cone is 120 π cm³
