A prop for the theater club’s play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round you

marta [7]

Volume of cone formula: V = PI x r^2 x h/3

Volume of sphere formula: 4/3 x PI x r^3

Cone: 3.14 x 9^2 x 9/3 = 763.02 cubic inches

1/2 sphere: 1/2 x 4/3 x 3.14 x 9^3 = 1526.04 cubic inches.

Total volume : 1526.04 + 763.02 = 2289.1 cubic inches

Laura answered 27 questions correct on a test on her test and scored 90%. How many questions where on the test?

Nadya [2.5K]

The number of questions in the test is 30

Step-by-step explanation:

Let's call the total number of questions in the test N.

We know that Laura answered 27 questions, and these 27 questions represent the 90% of the test.

Therefore, we can say that 27 is the 90% of N.

Re-writing the percentage as a fraction,

$90\% = 0.90$

This means that:

$0.90 N = 27$

And now we can solve for N to find the number of questions in the test:

$N=\frac{27}{0.90}=30$

A) 5.23, 7.89, 10.22, 34.98, 51.02, 51.22 because the closer a decimal is to 99 the larger it is.

B) 128+34.98+51.02+51.22=265.22
265.22-5.23-10.22-7.89=241.88
