Answer:
66π in²
Step-by-step explanation:
Area of one circular base: πr² ⇒ π3² ⇒ 9π
Area of the two circles: 9π + 9π = 18π
We know that the length of the rectangle is 8 in, but we still have to find width. The width of the rectangle is the circumference of either circle:
Width of rectangle: 2πr ⇒ 2π3 ⇒ 6π
Area of rectangle: 6π · 8 = 48π
Total Surface Area: 48π + 18π = 66π in²
Total Surface Area (using the π symbol on a calculator)≈ 207.345 in²
Hopefully this helps!
Answer:
OB=4
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
4x+5−5=21−5
4x=16
Step 2: Divide both sides by 4.
4x/4=16/4
x=4
