Answer:

20.3cm^2

Step-by-step explanation:

Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2

Díameter is 2 inches = 5. 08cm

But radius = diameter /2

Radius = 5.08cm /2

Radius = 2.54cm

Hence Area of bulleyse = 3.14 x (2.54) ^2

= 3.14 x 6. 451 cm^2

= 20.256 cm^2

=20.3cm^2 (to nearest tenth)

Website A gets 5,000,000 hits in one day. Website B gets 4,000 hits in one day. Approximately how many times more hits does Webs

ArbitrLikvidat [17]

Answer:

<u>1,250</u> times more hits does Website A get than Website B.

Step-by-step explanation:

Given:

Website A gets 5,000,000 hits in one day.

Website B gets 4,000 hits in one day.

Now, to find the times more hits Website A get than Website B.

Website A gets hits in one day = 5,000,000.

Website B gets hits in one day = 4,000.

So, to get the number of times more Website A get than Website B we divide Website A gets hits in one day by Website B gets hits in one day:

$5,000,000\div 4,000$

$=1,250.$

Therefore, 1,250 times more hits does Website A get than Website B.

Find the surface area of a pentagon-based pyramid with slant height of 11 m.

Ronch [10]

Answer:

108.75 square meter.

Step-by-step explanation:

<h3>Surface area of pentagon based pyramid:</h3>

$\sf \boxed{\text{\bf Surface area of pentagonal pyramid = $ \bf \dfrac{5}{2}*b*(a + s)$}}$

Here, b is the base length of the pyramid. b = 3 m

a is the apothem of the pyramid. a = 3.5 m

s is the slant height of the pyramid. s = 11 m

$\sf Surface \ area = \dfrac{5}{2}*3*(11 + 3.5)$

$\sf = \dfrac{5}{2}*3*14.5\\\\ = 108.75 \ m^2$

lina2011 [118]

Answer:
