Answer:

Volume of cone = 90 ft³

Step-by-step explanation:

diameter of cone = 6ft

radius of cone = 3ft

height = 10ft

Volume of cone = $\frac{\pi r^2h}{3}$

V = (3 × 3 × 3 × 10)/3

V = 270/3

V = 90 ft³

lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together

mezya [45]

Answer:

$\frac{5}{6}$ quarts

Step-by-step explanation:

Total amount of drinks = $\frac{1}{3}$ + $\frac{1}{2}$

You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.

$\frac{1}{3}$ + $\frac{1}{2}$ = $\frac{2}{6}$ + $\frac{3}{6}$

Now we can directly add them together while keeping the denominator the same.

$\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$ quarts

The expression, involving exponents , to represent the shaded area, in square inches, diagram. Then use that expression to calcu

mart [117]

Answer:

The shaded area is $23\ in^{2}$

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

$A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})\\ \\A=(2^{2})(3^{2}) -(3^{2} +2^{2})$

Calculate the shaded area

Remember that

$3^{2}=9\\ 2^{2}=4$

substitute

$A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}$
