- Surface Area of a Sphere: SA = 4πr²
- Diameter: d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
SA = 23 in²
<u>Step 2: Find </u><em><u>r</u></em>
- Substitute [SAS]: 23 in² = 4πr²
- Isolate <em>r </em>term: 23 in²/(4π) = r²
- Isolate <em>r</em>: √[23 in²/(4π)] = r
- Rewrite: r = √[23 in²/(4π)]
- Evaluate: r = 1.35288 in
<u>Step 3: Find </u><em><u>d</u></em>
- Substitute [D]: d = 2(1.35288 in)
- Multiply: d = 2.70576 in
- Round: d ≈ 3 in
Answer: C is about 100.53
Explanation:
C=2πr
C=2(3.14)(16)
C is about 100.53
Answer
sequence -28,-34,-40
1st term = -28
comman difference = -34 - (-28) = -6
comman term = a + (n-1)d
a= first term
d= difference
comman term = a + (n-1)d
= -28 + (n-1)(-6)
= -28 -6n +6
= -22-6n
1st term --> n =1 = -22 -6.1 = -22 -6 =-28
2nd term --> n =2 = -22 -6.2 = -22 -12 =-34
81st term --> n =81 = -22 -6.81 = -22 -486 = -508
