Step-by-step explanation:
The perimeter of the given circle is 25.1 square cm.
Step-by-step explanation:
- From the given diagram, the radius of the given circle is 4 cm.
- The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142
- The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm. Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.

Answer:
- 150.72 cm³
- 314 cm³
- 160 cm³
- 48 cm³
Step-by-step explanation:
Put the given numbers in the relevant formula and do the arithmetic.
<u>right cylinder</u>
V = πr²h = 3.14(4 cm)²(3 cm) = 3.14×48 cm³ = 150.72 cm³
<u>cone</u>
V = 1/3πr²h = 1/3(3.14)(5 cm)²(12 cm) = 3.14×100 cm³ = 314 cm³
<u>pyramid of unknown shape</u>
V = 1/3Bh = 1/3(16 cm²)(30 cm) = 160 cm³
<u>square pyramid</u>
V = 1/3s²h = 1/3(3 cm)²(16 cm) = 48 cm³

Answer: 41 inches by 6 inches
Step-by-step explanation:
A poster is in form of a rectangle and the area is length × breadth.
If the area of the poster is 240in² with 1 inch margins at the bottom and sides and 2in margin at the top.
The extra length of the poster will be 1-in at the bottom plus 2-in margin at the top making additional height of 3-inches.
Also, the extra breadth the 1-in at the sides to give breadth of extra 2-inches in total.
The area of the extra length and breath will be 3inches × 2inches to give 6inches.
The area that will give the exact dimension will be 240inches+6inches = 246inches
The dimension an be 41inches by 6inches
