Answer: 133/2π
Step-by-step explanation:
<u>Area of ends:</u>
Area of Circle = πr²
π3.5²=49/4π
There are two ends so you multiply that by 2 to get 49/2π
<u>Area of Rest:</u>
First, you need to find the circumference using the equation: πd
πx7=7π
Then to find the area you just need to multiply 7π by the height
7π x 6 = 42π
<u>Total surface area</u>
You now just need to add them together
49/2π + 42π = 133/2π
Answer:
standard form is use to make subtract and addition easy
Step-by-step explanation:
hope it helps
first one because you’re multiplying everything inside the parenthesis by 3
What am I suppose to do so I can help you?
Solution:
<u>We know that:</u>
- Radius: 18 yards
- πr² = Area of circle
- π = 3.14
<u>Finding the area of the circle:</u>
- (π)(r²) = Area of circle
- => (3.14)(18²) = Area of circle
- => (3.14)(324) = Area of circle
- => Area of circle = 3.14 x 324 = 1017.36 yards²
