Anne wants to fill 12 hanging baskets with compost. Each hanging basket is a hemisphere of diameter 40 cm.
murzikaleks [220]

Answer:

no

Step-by-step explanation:

Steps to answering this question

  1. determine the volume of the 12 basket

volume of a hemisphere = (2/3)πr^3

n = 22/7

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = 40/2 = 20 cm

volume of one hemisphere = (2/3) x (22/7) x (20^3) = 16,761.90 cm^3

volume of the 12 baskets = 16,761.90 cm^3 x 12 = 201,142.86 cm^

2. convert the litres of compost to cm and multiply by the total bags of compost

1 litre = 1000cm

1 bag of compost = 50 x 1000 = 50,000

4 bags of compost = 50,000 x 4 = 200,000 cm

3. compare which figure is higher. the figure gotten in step 1 or 2

201,142.86 cm^3 is greater than 200,000

there is no enough compost

A serving of ice cream contains 8500 calories. 1500 calories comes from fat. What percent of the total calories come from fat?
Genrish500 [490]
Perfect :)

Again, 1500/8500 ≈ 17.64%.

Again, write about 17.64% as, though i'm not sure about your teachers, but my teachers used to take marks off for that...
