Answer:
2n+8=25
Equation
Step-by-step explanation:
n=8.5
This is the answer
We know that
circumference=2*pi*r
for r=3 in
circumference=2*pi*3------> 18.84 in
if 2*pi radians (full circle) has a length of--------> 18.84 in
7*pi/3 radians-----------------> x
x=7*pi/3*18.84/(2*pi)-------> x=21.98 in
the answer is
21.98 in

Answer:
Using identify (a+b)(a-b) =a²-b²
Ur answer is (9b-1)(9b+1) =81b²-1
Volume is a three-dimensional scalar quantity. The volume of the triangular prism is 66cm².
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the length of the triangle is 4cm, while the width of the triangle is 11cm, therefore, the area of the base of the triangle will be,
Area of triangle = 0.5 × 4cm × 11cm
Area of triangle = 22 cm²
Now, the volume of the prism with a base area of 22cm² and a height of 3 cm is,
Volume of the triangular prism = 22cm² × 3cm = 66cm³
Hence, the volume of the triangular prism is 66cm².
