Answer: if ur looking 4 the surface area, then its 216 cm2.

Step-by-step explanation:

a= 1/2 b h

a= 1/2 (6) (4)

a= 12

12x2=24

a=lw

a= 12(5)

a= 60

60x2= 120

a=lw

a= 6(12)

a= 72

24+72+120= <u>216</u>

A circle's radius is increased by 10%. By what percentage does its area increase
Vladimir79 [104]
Answer: 21%

Explanation: Let the radius of the circle =R therefore area of the circle = [pi][R * R]
Radius of the circle after 10% increase =R+10% of R=R+R/10=11R/10
Therefore AREA of the circle with radius 11R/10 =[pi][11R/10*11R/10]=[pi][121R*R/100] Hence INCREASE in the AREA of the circle=[pi][121R*R/100]-[pi][R*R] =[pi] [R*R][121/100-1] =[pi][R*R][121-100]/100=[pi][R*R][21]/100 THEREFORE % increase in the area of the circle=[pi][R*R][21/100]/[pi][R*R] whole multiplied by 100=21 HENCE increase in the area of the circle =21% NOTE : pi is a constant whose value=22/7

The angle of elevation from a ball on a football field to the top of a 30-foot y'all goal post is 16 degrees 42'. How far is the
timama [110]

Answer:

  100.0 feet

Step-by-step explanation:

For an acute angle in a right triangle, the cotangent function is the ratio of the adjacent side to the opposite side:

  cot(16°42') = (distance to goal)/(30 ft)

Multiplying by the denominator, we have ...

  (distance to goal) = (30 ft)cot(16°42') = (30 ft)(3.33317) ≈ 100.0 ft

The football is 100.0 feet from the base of the goal.

_____

cot(16°42') = tan(73.3°)

At the local department store sweaters have been reduced to $15 this price is at 75% of the original price for sweaters given th
BartSMP [9]
Since 75% = 3/4
then $15 = 3/4 of the original price

Divide 15 ÷ 3 to get the 25% of the original price
(1/4 of the price)

15 ÷ 3 = 5

$5 is the 25% of the original price

so, if 25% + 75% = 100%
then $5 + $15 = $20

The original price for the sweaters was $20.
