Answer:
Volume = 42 in.²
Step-by-step explanation:
Volume of the triangular prism = ½×b×h×l
where,
b = 4 in.
h = 3 in.
l = 7 in.
Plug in the values
Volume = ½ × 4 × 3 × 7
Volume = 42 in.³

Step-by-step explanation:
Answer:
86
Step-by-step explanation:
7. a
Given,
Diameter = 16 feet
So, radius = 16 feet/2 = 8 feet
Circumference = 2πr
So, circumference of this circle
= 2πr
= 2 × 3.14 × 8 feet
= 3.14 × 16 feet
= 50.24 feet
b.
Given,
Diameter = 16 feet
So, radius = 16 feet/2 = 8 feet
Area = πr²
So, area of this circle
= 3.14 × (8 feet)²
= 3.14 × 64 feet²
= 200.96 feet²
