Alex Ar [27]

Answer:

87.92 mm³

Step-by-step explanation:

The area of the base of the cylinder and cones is the same for all, the area of a circle of radius 2 mm:

B = π·r² = 3.14·(2 mm)² = 12.56 mm²

If we call the heights of the lower cone, cylinder, and upper cone h1, h2, and h3, respectively, then the total volume is ...

V = (1/3)Bh1 + Bh2 + (1/3)Bh3

Here is is convenient to factor out B and also 1/3, so we have ...

V = B(h2 + (1/3)(h1 +h3))

V = (12.56 cm²)·((5 +(2+4)/3) cm) = 7·12.56 cm³

V = 87.92 cm³

dsp73

Answer:

Step-by-step explanation:

2+3+4+5+6=20

20/20=4,000,000

2/20=?

2/20×4,000,000÷20/20=400,000

20/20=4,000,00

3/20

3/20×4000000÷20/20=600,000

20/20=4,000,000

4/20

4/20×4,000,000÷20/20=800,000

20/20=4,000,000

5/20

5/20×4,000,000÷20/20=1,000,000

20/20=4,000,000

6/20

6/20×4,000,000÷20/20= 1,200,000

2:3:4:5:6=400,000 :600,000: 800,000 : 1,000,000: 1,200,000

The ratio of Julia’s peas to Vlada’s peas was 3:2. After Julia gave 15 peas to Vlada, she still had 10 more peas than Vlada. How

Ksenya-84 [330]

The ratio of Julia's to Vlada's peas was 3:2.
1. Julia gave Vlada 15 peas.
2. Vlada had how many peas?
3. Vlada had 4:2 peas after Julia gave her 15 more peas. (3:2+15=4:2)
4. Julia still had 15 more than Vlada.
5. Julia had 5:7 because (4:2+15=5:7)
6. To find out the amount of peas she had BEFORE she gave Vlada the peas, you subtract 5:7 from 15. That would equal 4:2.
