Answer:

Therefore the Last option is correct

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

Step-by-step explanation:

Given:

Radius = r = 8 in

θ = 42°

To Find:

Area of Sector = ?

Solution:

We know that

\textrm{Area of Sector}=\pi (Radius)^{2}\times \frac{\theta}{360}

Substituting the given values in the formula we get

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

Which is the required Answer.

Therefore the Last option is correct

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

43×15= what is the correct answer
mario62 [17]
43 × 15 = 645.

First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2. 
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.

Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.

Work out the area of a circle with a radius 7.5cm take pie to be 3.142. Give your answer 2 decimal places
GalinKa [24]

Answer:

176.74 cm^2

Step-by-step explanation:

Area of a circle is πr^2

r= 7.5

π= 3.142

Area=3.142× 7.5^2

= 3.142 × 56.25

= 176.74 cm^2

Hence the area if the circle is 176.74cm^2
