Answer: A= 460 mm2
Step-by-step explanation:
Hi, since the circumference formula is :
C = 2 π r
Where r is the radius, we can solve the formula for the radius replacing with the value given:
76 =2 π r
76 / (2 π) = r
r = 12.1 mm
Now , we have to apply the formula for the area of a circle.
A = π r^2
A = π (12.1)^2
A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)

Explanation. The given triangle is an equilateral triangle. Hence, all angles are equal to 60°. x = 180° – 60° = 120°.
Answer:
the answer would be 40
Step-by-step explanation:
Well since the first expression says 8x(40+7) the answer would be 40 that is missing
Since your splitting 47 into 40 and 7 and multiplying both of them by 8 the answer would be 40
You wold add both together and then divide by 5 so the equation would be 52+46=98 98/5=19.6 so the answer is 19.6
Just divide 80 by 7 and see if you don’t get a whole number !
