The volume of the sphere is 900 cm³
Step-by-step explanation:
- Step 1: Given the diameter of the ball = 12 cm. Find radius.
Radius = diameter/2 = 12/2 = 6cm
- Use the formula for volume of a sphere to find the volume.
Volume of the ball = 4/3 πr³
= 4/3 × 3.14 × (6)³
= 904.32 cm³ ≈ 900 cm³ (nearest hundredth)
Answer:
Step-by-step explanation:
On a certain hot summer's day, 691 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $1260.75. How many children and how many adults swam at the public pool that day?
Circumference of a Circle = 2πr
2 π 5
approx 31.41
Area of a Circle πr^2
π5^2
Approx 78.53
So first you should find the area of the rectangle on the bottom.
18x12=216
Then find the area of the trapezoid. I believe the formula is A = a+b/2(h).
So do 10 + 18 = 28, divide by 2, which is 14, then multiply by the height, 6, and you get 84.
Now you add the area of both shapes together, 216+84=300.
300 ft is your answer.
