Answer:

538,3m^2

Step-by-step explanation:

first of all, I find it really disturbing to use 3,14 as pi but I'll try my best.

1) Determine the area of the rectangle;

h.b= area of a rectangle

so here

15m.30m = 450 m^2

the area of the circle = pi.r^2

so here

7,5m^2.3,14 = 176,625m^2

but we only need the half of it so 176,625m^2/2 = 88,3125m^2 ~ 88,3m^2

then we must sum them all up;

88,3m^2 + 450m^2 = 538,3m^2

What single percentage change is equivalent to a 12% increase followed by a 13% increase?
lozanna [386]

Answer:

A 26.56% increase.

Step-by-step explanation:

A 12% increase corresponds to a total of 112% of the original amount.

Hence, a 13% increase of the 112% of the original amount would be equal to 1.12*1.13 = 1.2656, which equates to 126.56% of the original amount.

Hence, the single percentage change would be a 26.56% increase.

Hope this helped!

What is the area of the given sector
Romashka-Z-Leto [24]
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.

Then, using the circle area formula, the area of the 1/9 circle would be: 
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57

I need help with this question on my geometry homework
Margarita [4]

Answer:

x = 250°

Step-by-step explanation:

Inscribed angle = ½(intercepted arc measure) (inscribed angles theorem)

x is intercepted arc measure

125° is the inscribed angle

Therefore:

125° = ½(x)

Multiply both sides by 2

2*125° = x

250 = x

x = 250°
