Answer:
Given - Radius of ring is 9 millimeters
To find - Circumference
Solution -
9 millimeters = 0.9 centimeters
Circumference of circle = 2 × pie × r
= 2 × 3.14 × 0.9
= 6.28 × 0.9
= 5.652
3.33333333 as a whole number is 3
1. A
2. should be 42?
3.???
4.27 apples left
5.B 1/4
Answer with Step-by-step explanation:
The radius of the bull’s-eye of the dartboard is 8 inches.
The radius of each concentric circle is 8 inches more than the radius of the circle inside it.
Radius of first circle=8 in.
Radius of second circle=16 in.
Radius of third circle=24 in.
Radius of fourth circle=32 in.
Area of C=Area of the third circle-Area of second circle
= π×24×24-π×16×16
= 320π sq. in.
Total area of dartboard=Area of fourth circle=π×32×32
=1024π sq. in.
P( the dart will hit in area C)= area of c/total area of dart board
=320π/1024π
= 5/16
Hence, correct option is:
B.5/16
By definition, the volume of a cone is given by:
V = (1/3) * (pi) * (r ^ 2) * (h)
Where,
r: cone radius
h: height of the cone
Substituting values:
V = (1/3) * (3.14) * ((8/2) ^ 2) * (9)
V = 150.72 cm ^ 3
Answer:
this paper cone cup can hold:
V = 150.72 cm ^ 3
