Answer:
A≈1206.37 cm²
Step-by-step explanation:
Radius = 12
Height = 16
Using the formulas
A= πrl+πr²
l = √r²+h²
A=πr(r + √h²+r²)=
π·12·(12+√16²+12²) ≈1206.37158cm²
Volume of a sphere- 4/3 x pi x r^3
So, we plug it in. 4/3 x pi x 9.36^3
Simplify that.
4/3 x pi x 820.025856
4.816 x 820.025856 = volume
3433.17491712 = volume.
Your answer is C) 3,433.17 units^3
If it is 0.9 meters long and then he cuts the pipe into 4 equal pieces, then you would just do the equaton: 0.9÷4 and the answer would be 0.225
If those numbers provided were the degree measurements, then z would be 102°. A triangle is 180°. 180°-54°-24°=102°.
Answer:
A.) -0.015x² + 0.365x + 1.116
Step-by-step explanation:
Using a graphing calculator, the quadratic regression equation obtained for the data in the table is :
General form of a quadratic regression equation :
A + Bx + Cx²
A = 1.115714
Bx = 0.3647x
Cx² = - 0.015x²
Hence, rounding to the appropriate number of decimal places, the quadratic regression equation becomes ;
-0.015x² + 0.365x + 1.116
