A bowl in the shape of a hemisphere has a volume of 144π cubic centimeters. What is the radius of the bowl?
Alla [95]

Answer:

6 = r

Step-by-step explanation:

V = \frac{2}{3}πr³                Use this equation to find the volume of a hemisphere

144π = \frac{2}{3}πr³           Divide both sides by \frac{2}{3}π

216 = r³                 Take the cube root of both sides

6 = r

Tan^2 70° -sec^2 70°​
kipiarov [429]

Answer:

-1

Step-by-step explanation:

We need to find the value of tan² 70° -sec² 70°​.

We know that,

\sec^2\theta-\tan^2\theta=1 ...(1)

We can write the given expression as :

tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)

=-(sec² 70°-tan² 70°)

Using identity (1)

=-(1)

= -1

Hence, the value of the given expression is -1.
