Option D:
Surface area of the cylinder = 753.6 cm²
Solution:
<u>To find the surface area of the cylinder:</u>
Given data:
Radius of the cylinder = 6 cm
Height of the cylinder = 14 cm
The value of π = 3.14
Surface area of the cylinder =
= 226.08 + 527.52
= 753.6 cm²
Surface area of the cylinder = 753.6 cm²
Option D is the correct answer.
Answer:
The surface area of square pyramid is 953.64 cm² .
Step-by-step explanation:
Given as for a square pyramid :
The height of pyramid = l = 15 cm
The base of square pyramid = x = 18 cm
Now,
The surface area of square Pyramid =
or , The surface area of square Pyramid =
Or, The surface area of square Pyramid =
Or, The surface area of square Pyramid = 324 + 36 ×
or, The surface area of square Pyramid = 324 + 36 × 17.49
Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²
Hence The surface area of square pyramid is 953.64 cm² . Answer
You can simplify the right side. Then, you need to take cube roots.
(m -4)³ = 1/(1/8) . . . rule of exponents
(m -4)³ = 8 . . . . . . .simplify
m -4 = ∛8 . . . . . . . take cube roots
m -4 = 2 . . . . . . . . use your calculator or knowledge to find ∛8
m = 6 . . . . . . . . . . add 4
The solution is m = 6.
_____
If you subtract the right side, you get a function of m that is zero when m has the right value. This graph shows that value is m = 6.
