=========================================================
Explanation:
The rule we use is
where 'a' is the base, m stays in the role of the exponent, and n plays the role of the root index (eg: n = 3 is a cube root, n = 4 is a fourth root, and so on).

or in this case,
Answer:
879cm
Step-by-step explanation:
Radius is 35cm.
Diameter is 70cm.
Pie/Pi is 3.14 and so on.
Perimeter of circle:70×3.14=219.8
219.8×4=879.2
Round Off:879.2cm
122.5.
A=b x h/2. A=122.5 b=7
A x b=h
122.5 x 7 =122.5
