The equation of a circumference is 2

r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34
Total surface area = 2 * circular base + circumference * height
= 2 * pi*(4)^2 + 8pi * 12
= 32pi + 96pi
= 128pi answer
Answer:
B
Step-by-step explanation:
2/5 (10x + 15) = 26
Distribute the 2/5
4x + 6 = 26
4x = 20
x = 5
1 split into two equal parts so the answer is 2
