Answer:
A = 388.58 cm^2
Step-by-step explanation:
For a cone whose base has a radius R, and a hypotenuse S, the area is:
A = pi*R^2 + pi*R*S
Where pi = 3.14
In this case, we can see that the diameter is: 15cm
Then the radius, half of the diameter, is:
R = 15cm/2 = 7.5cm
The hypotenuse is 9cm, then S = 9cm
A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2
Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:
A = 388.58 cm^2
19) B
20) D
21) A
22) B
23) C
24) C
the answer to it is 24X squared but the answer to your question is both are ok they both give u 12X which is 24X squared the way u wrote it lol
Answer:
x = -7
Step-by-step explanation:
4(1 - x) + 2x = -3 (x + 1)
4 - 4x + 2x = - 3x - 3
- 4x + 2x + 3x = - 3 - 4
x = -7
