7 0

Answer:

C = 21.98 ft^2

A  = 38.465 ft^2

Step-by-step explanation:

The  diameter is 7 ft

The radius is 1/2 of the diameter so 1/2 *7 = 3.5 ft

Circumference = pi*d

C =pi* 7

C =3.14 *7

   = 21.98 ft^2


A = pi*r^2

  = 3.14 (3.5)^2

   = 3.14 (12.25)

   = 38.465 ft^2

Find the indicated probability.
LekaFEV [45]

Using it's concept, it is found that there is a 0.152 = 15.2% probability that they are both Democrats.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Two voters are selected, each with 39% probability of being Democrats, hence the probability of both being Democrats is given by:

p = (0.39)² = 0.152.

0.152 = 15.2% probability that they are both Democrats.

What’s the correct answer for this question?
Fofino [41]

Answer:

C.

Step-by-step explanation:

According to theorem, "the measure of central angle of minor Arc of a circle is doubleto that of the angle subtended by the corresponding major Arc."

So

m<AOB = 2(m<AZB)

m<AZB = M<AOB / 2

m<AZB = 68/2

m<AZB = 34°
