Area of a Circle: A = πr

r is radius

Step-by-step explanation:

Step 1: Define

r = 14.5

Step 2: Find Area

Substitute in r [Area of a Circle]: A = 14.5π
Approximate π: A = 14.5(3.14)
Multiply: A = 45.53

Express the following in exponential notation: (-13) X (-13). 35 times

miv72 [106K]

Answer:

$(-13) * (-13) = (-13)^{2}$

$35 * 35 = 35^{2}$

Step-by-step explanation:

Given

$(-13) * (-13)$

Required

Express as an exponential notation

$(-13) * (-13)$

Apply the following law of indices

$x^a * x^b = x^{a+b}$

This gives:

$(-13) * (-13) = (-13)^{1+1}$

$(-13) * (-13) = (-13)^{2}$

The second complete is incomplete; However, I'll assume it is: 35 times 35

$35 * 35$

Using the same law applied in (1) above:

$35 * 35 = 35^{1+1}$

$35 * 35 = 35^{2}$

A player at a basketball camp set a goal to make 55% if his shots. If he has 120 attempts, how many shots would he need to make

Pavel [41]

Answer: 66

Step-by-step explanation:

From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.

The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:

= 55% × 120

= 55/100 × 120

= 0.55 × 120

= 66

He would need to make 66 shots
