Radius is always half of the diameter.
22 mm/2= 11 mm
Final answer: Radius=11 mm
31) ($6 * 2) + $6.25 + $4.25 + $20 = $42.50
32) $50 - $8.25 - $4.25 -$4.25 - $20 = $13.25
33) 6 * 15.99 = 95.94 | $100 - $95.94 = $4.06
34) $10.50 * 8 = 84 | $100 - $84 = $16
Hope this helps! ^^
Answer: The surface area is 65 cm.
Answer:
A +7= F
Step-by-step explanation:
A is his current age, and he gains, or adds seven years he will be F or his future age.
Answer:
See below ~
Step-by-step explanation:
<u>Things to Find</u>
- Volume of Toy
- Difference of Volumes in Cube and Toy
- Total Surface of Toy
<u>Volume of Toy</u>
- Volume of Hemisphere + Volume (Cone)
- 2/3πr³ + 1/3πr²h
- 1/3πr² (2r + h)
- 1/3 x 3.14 x 16 (8 + 4)
- 1/3 x 50.24 x 12
- 50.24 x 4
- <u>200.96 cm³</u>
<u></u>
<u>Volume of Circumscribing Cube</u>
- Edge length is same as diameter
- V = (8)³
- V = 512 cm³
<u>Difference in Volume</u>
- 512 - 200.96
- <u>311.04 cm³</u>
<u></u>
<u>Slant height of cone</u>
- l² = 4² + 4²
- l² = 32
- l = 4√2 cm = 5.6 cm
<u />
<u>Surface Area of Toy</u>
- CSA (hemisphere) + CSA (Cone)
- 2πr² + πrl
- πr (2r + l)
- 3.14 x 4 (8 + 5.6)
- 12.56 x 13.6
- <u>170.8 cm²</u>
