Answer:

19683

Step-by-step explanation:

As the formula of the geometric sequence:

$a_{n} =a_{1} *r^{n-1}$

In the sequence of 1, 3, 9..., you have a1 = 1 and r = 3. Therefore:

$a_{10} =1 *3^{10-1} = 3^{9} =19683$

The volume of cone is calculated by the formula $V= \frac{1}{3} \pi R^2H$ , where H is a height of cone and R is a radius of the bottom.
In your case, R=3 cm and R=7 cm. Then $V= \frac{1}{3} \pi* 3^2*7= \frac{63\pi}{3} =21\pi$ .

Marcus used a calculator to evaluate 54 ÷ 6 + 3 × 2 by entering

fiasKO [112]

Answer:

Step-by-step explanation:

The calculator is actually correct because he entered division before addition.

Following the Bodmas rule of

B= Brackets O= Off D= Division M= Multiplication A= Addition S= Substraction

And from the question 56÷6 + 3 x 2, when bodmas is applied here it becomes ; (56÷6) +( 3 x2)

And when brackets is removed , it becomes

9+6 = 15.
