The area of triangle is 210 feet and the height is 30 feet write an equation to find the base of the triangle and use it to solve the problem

Equation:  0.5*30*b = 210

               Base length: 14

Step-by-step explanation: The formula of the area of a triangle is 1/2*b*h, so we can use that and the information given to make a formula then solve.

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
