Find the total surface area of this cylinder . Give your answer to 1 decimal place 7cm 15 cm
Leto [7]

Answer:

Step-by-step explanation:

r = 7 cm

h = 15cm

pi = 3.14

Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).

Area = 2* pi *r^2 = 2 * 3.14 * 7^2

Area = 2 * 3.14 * 49

Area =                                                        307.72  Don't round this.

Cylinder body

Cylinder body = Circumference * h = 2*pi * r * h

Cylinder body = 2* 3.14 * 7 * 15

Cylinder body =                                      <u> 659.4</u>

<u />

Total =                                                      967.12

Rounded        967.1     Answer

Please solve for me. C=1/2x(a+w)
Gnoma [55]

Answer:

C= 1/(2ax+2aw)

Step-by-step explanation:

C=1/2x(a+w)

Multiply a and w by 2x. Take note of the sign.

C= 1/(2ax+2aw)

when writing your answer, you don't need the brakets. I just put them so you'd understand that all those characters in the bracket are the denominator.

Please rate 5 stars, thanks, give brainliest. Thanks.

If cos A = k, then the value of the expression (sin A)(cos A)(tan A) is equivalent to:
sukhopar [10]

Answer:

1-k^2

Step-by-step explanation:

tan A= sin A/cos A

(sin A)(cos A)(sin A/cos A)=(sin A)^2

(sin A) ^2 + (cos A) ^2= 1

(sin A) ^2=1-(cos A) ^2

(sin A)^2= 1 - k^2
