Find the volume of a right circular cone that has a height of 2.3 in and a base with a diameter of 3.6 in. Round your answer to the nearest tenth of a cubic inch.

V = 7.81 cubic inches

Step-by-step explanation

The formula for right circular cone is

V = πr^2 h/3

V = volume of the cone

π - pie

r = radius of the cone

h = height of the cone

We are provided with

h = 2.3in

d = 3.6in

π = 22/7

First, we calculate the radius

d = 2r

r = d/2

r = 3.6/2

r = 1.8

Then we can use the formula

V = πr^2h/3

V = 22/7 * 1.8^2 * 2.3/3

V = 3.142 * 3.27 * 0.767

V = 7.80812136 cubic inches

According to the question, we are asked to round off to nearest tenth cubic inches

V = 7.81 cubic inches

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
