- Radius: r = d/2
- Surface Area of a Sphere: SA = 4πr²
Step-by-step explanation:
<u>Step 1: Define</u>
d = 19 cm
<u>Step 2: Find </u><em><u>SA</u></em>
- Substitute [R]: r = 19 cm/2
- Divide: r = 9.5 cm
- Substitute [SAS]: SA = 4π(9.5 cm)²
- Exponents: SA = 4π(90.25 cm²)
- Multiply: SA = 361π cm²
- Multiply: SA = 1134.11 cm²
- Round: SA ≈ 1134 cm²
you can't really see the question it's too blurry
Find the rectangle area
A = 8*4 = 32 in²
Find the height of trapezoid
8-4 = 4 in
Find the area of trapezoid
(5,3+8)*4/2 = 13,3*4/2 = 53,2/2 = 26,6 in²
Find the figure area
26,6+32 = 58,6 in²
Answer:
x^6 + 2x^3 -2x^2 -8x + 4
Step-by-step explanation:
Okay, so we need to multiply f and g.
Since you said asap, I won't do the long explanation...
x3 -4x 2
x2 x6 -4x2 2x2
2 2x3 -8x 4
x^6 + 2x^3 -2x^2 -8x + 4
